Part 4 Voice Recording In Audacity

The steps below will guide you through recording a voice file using the audacity sound editing software.

NOTE: The quality of voice recordings are subject in the main to two factors.
1. The quality of the microphone used.
2. The quality of the soundcard used.
There are other considerations which you should also take into account.
1. Experiment with the distance between your mouth and the microphone.
2. Try to place the microphone away from other equipment such as pc towers etc which can cause unwanted rumble on the recording.
3. The shorter the microphone’s lead the better, longer leads equal increased impedance.
4. Matching up the inputs can also help, a mono microphone into the “Microphone” socket on the soundcard, a stereo microphone into the “Stereo Line In” socket etc.
5. Remember too, it might seem obvious but make sure there are no external noise sources such as radios, tv, boilers, kettles etc in the immediate vicinity.
As you are all using different equipment, there is no hard or fast rule here, experimentation is the key.

Voice Recording Procedure:
1. With the microphone connected, open audacity.
2. A blank file, track), will be loaded by default.
3. Press the letter R to commence recording.
4. The program is now actively recording.
5. Before speaking, leave a 2 second gap or so.
6. This is to allow your screen reader to speak and then stop speaking and also to give you some blank noise at the beginning of your track for denoising purposes.
7. Now speak into your microphone.
8. When you have finished speaking, press the Space Bar to stop recording.
9. Now press the Space Bar and you should hear your recording.
10. Now name and export to your chosen format in the usual way.

Part 5 Multi tracking In Audacity

1. Load audacity.
2. Press ctrl+shift+I to import the first file, the music track you wish to use for the background track.
3. Press ctrl+shift+I to import the second file, the voice track .
4. Now press the space bar to play the files and you should hear both the music and the voice file together.
5. you will want to move the voice track to the right in order to have some music playing by itself
6. If so, ensure that only the voice file is selected and press ctrl+X to cut the file.
7. Now press the space bar and you should hear only music.
8. When you reach the point at which you want to paste the speech back into the multitrack interface, mark the track with a press of the [ key.
9. Now stop the track.
10. Now press ctrl+v to paste the voice track in your desired location.
11. Now press the home key to take the whole thing back to the start position.
12. Play the track and you should hear only the background music first, then the background music and your voice track and then the background music again.
13. So, you are now half done.
14. To make the piece sound a little more professional, it is advisable to give some prominence to the vocal against the background music.
15. This is best achieved by using the Autoduck tool.
16. To do this, ensure in the multitrack interface that only the music track is selected.
17. At this point, the music track becomes your control Track , though Audacity will not tell you this.
18. Press an alt+C to open the effects menu and press V or arrow down to Volume And Compression sub-menu .
19. Now arrow down once and you will land on Autoduck .
20. Press the Enter key to activate this control.
21. If you hear the dreaded Windows Error sound, as you may, escape and go back to the tracks in the multitrack interface and check their selection status.
22. It often happens here that for some reason you find both tracks are selected.
23. Ensuring that you only have the music track selected, return to the Autoduck control.
24. After pressing the Enter key on Autoduck , a dialogue will present itself.
25. There are many alterations you can make here, but for now I advise just accepting the defaults and tabbing to the OK button and pressing Enter to activate the control.
26. You will probably hear a percentage dialogue counting up as the process is active.
27. After the process is complete, play the file.
28. What you should now hear is, only music playing at full volume, music fading down in volume to give accentuation to the voice track, your voice track with the softened music playing in the background and then after the voice has finished speaking, the music only at full volume again.
29. The next step is to mix and render the files to one stereo track.
30. To do this, press an Alt+T to open the Tracks menu.
31. Now arrow down until you hear Mix & Render and press the Enter key to activate this control.
32. You will probably hear a dialogue counting up through the mix and render process.
33. Once the process is completed, you will find various tracks in the multitrack interface.
34. This is not a problem, for as long as you hear Table Mix , the mixing and rendering process has completed successfully.
35. Now export the file in the normal manner to either MP3 or Wav format.
36. during the export you may hear a warning from Audacity that you are mixing down to one stereo track, this is fine, just press the Enter key here to accept and complete the exportation of the file.
37. Now close audacity and do not save any changes.
38. reopen audacity and use the traditional Ctrl+O keystroke to open your newly created file.
39. You are now returning to the Ctrl+O method of file opening as you are only opening a single file.
40. Play the file and check it sounds ok.
41. The one problem you may have of course is that the file is too long, i.e. it plays for a long time after the section of mixed voice and music.
42. Use the usual selection and deletion controls you’ve learned already to trim the file to the desired length.
43. You might also wish to apply fades at the beginning and ends, this is a matter of personal choice.
44. Once you’ve done all that remember to re-export it under a new name.
45. Finally, to check all is well, launch the file from Windows Explorer , to play the file in your default player.

Part 6Fading With Audacity

Fading In:
1. Start the file playing with a press of the space bar.
2. Allow the file to play to the point at which you want the introductory fade in to end and the normal volume of the file to take over.
3. At this point, press the right square bracket key.
4. the file will continue to play, pressing the space bar will stop the file.
5. Now press the space bar to play the file and it will play up to the point at which you inserted the right marker with the right square bracket key only.
6. Now make sure you select this portion of the file with the keystroke Shift+Home .
7. Depending on your screen reader and its configuration, you may or may not hear selected spoken.

2. The file will continue to play, pressing the space bar will stop it.
3. Pressing the space bar should now play the file from the marker point to its end.
4. Once you are sure you have marked the file in the correct place, do the keystroke Shift+End to select the file from the marker point to the end of the file.
5. Depending on your screen reader and its configuration, you may or may not hear select spoken.
6. Now press the keystroke Alt+C to open the Effects menu.
7. Now press a F to go to the FadeSub-Menu .
8. At this point, pressing an F will take you to the fade in control as previously.
9. Pressing the F a second time will take you to the fade out control.
10. You can also use the up and down arrow keys to navigate this menu.
11. Once on the fade out control, press the Enter key.
12. The program will now process the fade out.
13. Once processed, pressing the space bar at this point should allow you to hear from your marker to the end of the file with a fade out.

Part 7 Audacity Normalisation

It may occasionally be necessary to raise the volume in an audacity file.
Applying an overall increase in volume over the entirety of the file is called Normalisation , the steps below will guide you through the normalisation process.

With the file loaded,
1. press Ctrl+A to select the entire file.
2. press Alt+C 2 open the Effects menu.
3. Press V you will hear Volume and compression Sub-Menu .
4. Press N you will hear Normalise and press enter
You will now be presented with the normalisation dialogue.
The dialogue contains various settings, most of which are not essential for our operation.
The dialogue opens on an Offset setting which you can leave alone.
Pressing Tab once will take you to Maximum volume check box checked this is also fine.
Pressing Tab again will take you to an edit field which will dictate the normalisation value.
This field is usually by default at -0.1 or 0.0 , either of these is fine.
You can change the value in this field to a lower, eg, -0.5 or whatever, but it is not advisable to input Plus values into this field.
Plus values can incur unwanted distortion.
Now Tab to OK and press Enter .
Your file will now normalise, remember, depending on the size of the file the time taken to carry out the normalisation may vary from near-instant to quite a few seconds.
Once normalised, play the file again and check if it sounds ok.
Remember, to save the file after normalisation, preferably following a numbering convention.

Part 8 Applying Delay In Audacity

In audio editing, delay is the process of extending the length of a section of an audio file by enabling it to repeat a given number of times.
This is often used to give emphasis to a section of an audio file such as a trailer, song etc.

NOTE The use of delay is absolutely governed by personal preference, the guide below will take you through the steps needed to set up a delay, you will need to experiment with the delay dialogue to achieve your own preferred sound.

1. With audacity open, load an audio file.
2. You may find a short speech file most useful for this example, as it will provide an easy starting point and will minimise on track navigation.
3. Now with the file loaded, we will apply delay to the entire audio track.
4. Press Ctrl+A to select the entire file.
5. Now press the keystroke Alt+C to open the Effects menu.
6.Press D for Delay and reverb Sub-Menu”.
7. You will find three options, Delay, Echo, and reverb.
8. You need the Delay option.
9. Press the Enter key on Delay
10. The Delay dialogue will now open.
11. With the Regular setting selected, this is fine.
12. Important to note here, is that nearly all of the settings controls have two means of access.
13. The controls are grouped together in pairs each with an edit box in which you can type a value and a slider control with which you can adjust the individual setting.
14. In this example, we will use the slider controls in the main.
15. Now press the Tab key twice.
16. You will hear Decay, and a percentage value, the value will probably be defaulted at 28%.
17. Use the Page Up key to slide this value to 8%.
18. This normally takes two pushes of the Page Up key.
19. Now press the Tab key twice.
20. You will now hear Delay Time and a percentage value, the value will probably be defaulted to 10%.
21. This is fine to leave alone, but if you do want to adjust this control, once again it’s the Page Up and Page Down keys you need to press.
22. Now press the Tab key twice.
23. You will hear Pitch Change Per Echo.
24. For now, leave this alone.
25 Now press the Tab key once.
26. You will find yourself in an edit field which dictates how many repeats you will apply.
27. This is usually defaulted to 5.
28. If you wish to change this number you need to type in a number from the number row on your keyboard.
29. typing in an 8 works well here.
30. Now find the OK button and press the enter key to activate.
31. You may hear a percentage count whilst the delay is being processed.
32. Once completed, press the Space Bar to play the file and listen to the results.
33. If successful, there should be a lot of repeating going on.
34. In fact, you might find the repeating a little too much and wish to fine tune it some more.
35. Let’s redo the operation with just the tail end of the audio “Delayed”.
So, press the keystroke Ctrl+Z to undo the Delay and return the file to normal.
36. Now, play the file, this is why a short file is better here and when it is almost at its end, press the ] key.
37. Now press the keystroke shift+Home to highlight the bulk of the file.
38. Now Cut this to the clipboard with the keystroke Ctrl+X.
39. Now press the keystroke Ctrl+N to open a new file.
40. When the new file is opened, paste from the clipboard with a Ctrl+V.
41. You have done this to make two separate files, but don’t worry, we’ll join them back up soon.
42. Be warned, Audacity may decide to give your new file the same name as the current file.
43. If you are in doubt as to which file has focus, pressing the Space Bar will play the file for you in order to enable you to check.
44. Now press the keystroke “Alt+Tab” to return to the file from which you cut the bulk of the audio.
45. Press the Space Bar to check you have the correct file in focus.
46. If you have, you should hear only the tail end of the original file.
47. Now repeat steps 5-11 , to access the Delay procedure.
48. Make sure you press Enter on the OK button.
49. Press the Space Bar to listen and the tail end of your file should now be delayed.
50. Now, use the keystroke Ctrl+A to select all of this tail end file.
51. Now either copy or cut with Ctrl+C or Ctrl+X.
52. Now press the keystroke Alt+Tab to move to the new file.
53. Press the Space Bar to listen and you should hear the audio you cut.
54. Now press the End key.
55. You are now at the end of this file and ready to paste in your Delayed tail end section.
56 Paste with the keystroke Ctrl+V.
57. Now press the Home key to go to the start point of this file.
58. Now press the Space Bar to play the file.
59. If successful, you should hear the bulk of the file play normally, then at the tail end of the file you should hear the Delay.
60. This partial delaying of a file can often deliver more impact.
61. If you like the results, export this file to save and then close Audacity without saving changes.
62. If you wish to change the pitch of the Delayed audio, repeat steps 5-11 to access the Delay dialogue and press the Tab key 6 times to get to the Pitch slider.
63. This slider, like the others is controlled with the Page Up and Page Down keys.
64. the higher the percentage number, the higher will be the resultant pitch.
65. 50% represents no change in pitch.
66. so correspondingly, percentages below 50% will result in a lowering of pitch.
67. Again, make sure to press the enter key on the OK button to complete any delay process.

Part 9

Denoising A File In Audacity

Denoising is the process of removing unwanted background noise from an audio file. Following the steps below will guide you through this procedure using the audacity sound editor.

NOTE: In order to make this procedure work you will need a file with discernable noise to remove, the file “Bad Guitar.wav” on the tafn website should work well with this exercise.

1. Open audacity and load the file.
2. Press the space bar to run the file and you will hear a loud hum before the guitar starts to play.
3. If you listen to the entire file, (it’s very short), you will hear the hum is present throughout the entire file.
4. Now play the file again, but after about 1 second, press the right bracket key.
5. The file will continue to play, you can stop it if you want with the space bar.
6. Now press the space bar to run the file again.
7. This time it should only play for a second or so before stopping and all you should hear is the hum.
8. You have instructed the program to focus only on this section.
9. Now press the keystroke “Shift+Home”.
10. You have now selected this piece of audio which you will now work on.
11. You may hear the word “Select”, but you may not, this seems to depend on different screen readers and their configuration.
12. Now press the keystroke “Alt+C” to open the “Effects” menu.
13. Press “N” you will hear “Noise removal and repair Sub-Menu”.
14. Press “N” until you hear “Noise reduction ” press the “Enter” key.
15. You will now be presented with a dialogue which is asking you to confirm the noise you wish to select.
16. Press the “Enter” key once and you will be returned to the file.
17. Now, do the keystroke “Ctrl+A” to select the entire file.
18. This is necessary to tell the program that the selected noise is to be removed from wherever it occurs in the file.
19. Ok, some repetition now.
20. Press the keystroke “Alt+C” to open the “Effects” Menu.
21. As previously, Press “N” you will hear “Noise removal and repair Sub-Menu”.
22. Now press “N” until you hear “Noise Removal ” and press the “Enter” key.
23. Now press the “tab” key until you hear “OK”.
24. Press the “Enter” key and the denoising process will begin.
Depending on your machine’s speed, you may or may not hear a percentage count up.
Either way, give the program a few seconds to denoise this file.
Remember, this is a very short file, larger files will take longer to process.
25. Now play the file using the space bar and you should hear nothing for a second or so then a clear guitar sound with no hum.
You have successfully denoised the file.

Part 10 Applying High Pass filter In audacity

High pass filtering can be very effective in “cleaning up” some older and somewhat “dull” sounding audio files.
It works by filtering out the lower “rumble” type noises often found particularly on audio files derived from old tape. It also sharpens up the top end of the audio.
The Audacity high pass filter can be very finely adjusted and I would urge you to play around with its configuration.
Here however we are going to use the defaults provided in audacity.

The steps below will guide you through the process.

1. With audacity opened, load a file.
2. Play the file, or at least part of it in order to get a feel for how it sounds.
3. Now stop the file and press the keystroke “Ctrl+A” to ensure the whole file is selected.
4. Now press the keystroke “Alt+C” to open the “Effects” menu.
5. Press “E” For “EQ and filter”
6. Press “H” to “High Pass Filter…” and press the “Enter” key to open the dialogue.
7. Now Tab to “OK” button .
8. When you locate the “OK” button, press the “enter” key to activate.
09. Depending on the length of the file, you will hear the filtering process counting up through its percentages.
10. Once completed, press the “Space Bar” to play the file again.
11. You should be able to hear a noticeable change in the clarity of the file.
12. Remember, this is the default setting and you can make many smaller or larger changes to the application of the filter if you wish.
13. If you wish to keep the alterations made to the file, remember to export it before closing Audacity.

Part 11 Trimming In Audacity

Trimming is the process of selecting a particular section of an audio track, then cutting away and disposing of the rest.
The steps below will guide you through the audio trimming process in Audacity.

NOTE: Unlike some other sound editors, once the trim command has been executed in audacity, the remaining audio will stay in its original location and has to be cut and pasted to the start of the track manually.

1. With Audacity opened, load an audio file of your choice.
2. You can load either MP3 or Wav, it doesn’t matter.
3. You will use the “[” and “]” keys to make your selection.
4. Play the file in the normal way with a press of the “Space Bar”.
5. When the file nears the point of your selection, press the “[” key to mark the left hand end, (start point), of the selection.
6. You can stop the file here and press “Space Bar” to restart it and ensure you are where you want to be.
7. Now with the file playing from the start of your selection, allow it to play on until you reach the end of the audio you wish to select and press the “]” key.
8. Stop the file playing.
9. Now press the “Space Bar” to listen to what you have selected.
10. If you are satisfied with your selection, you are now ready to perform the trim operation.
11. There are two ways to trim, you can either use the keystroke “Alt+E” to open the “Edit” menu” and arrow down to “Trim” and press the “Enter” key, or you can use the short cut keystroke “Ctrl+T”, either will do.
12. Once you have executed this command, all of the audio at either side of your selection will have been cut away, leaving you only with your selection.
13. You now need to move the remaining audio, (your selection), to the beginning of the track.
14. As your audio is still selected, all you need to do is cut and paste this audio.
15. Press “Ctrl+X” to cut the audio to the clipboard.
16. Now press the “Home” key to take you to the start of the track.
17. Now Paste with a “Ctrl+V”.
18. Now press the “Space Bar” to test that the operation has worked.
19. If successful, the file will now begin playing with the start of your selection and finish playing at the end of your selection.
20. The rest of the audio has gone.
21. Remember, if you want to keep these changes, you will need to re-export the file.
