In Audacity, most voice recording will be done as a mono or single channel sound track. The blue image on the Audacity tracks below is the wave form display of the audio track.
Audacity Stereo Tracks
Stereo Tracks include both a right and left channel as illustrated below. A stereo track is a group of two audio tracks that are grouped together. The top wave form is the left channel and the bottom form is the right channel.
When you edit a stereo track in Audacity, you'll be working on both channels at once. If you need to edit only one channel, you can split the stereo track into two mono tracks. You can split them using the Track Pop-Down Menu.
The Audacity Track Control Panel
The Track Control Panel appears directly to the left of every track. To delete the track, click on the "X" in the upper left corner. The title of the track appears just to the right of the "X". Clicking on the title brings you the Track Pop-Down Menu, allowing you to rearrange tracks and change various track options.
1. This item tells you the channel of the track (in this case it is stereo), and the sample rate (e.g. 44,100 Hz. is the audio CD rate).
2. 32-Bit Float - This indicates the quality of the sound file. 32-Bit Float is the highest quality. You could also see 16-bit here.
3. Mute Button - The Mute Button stops the track from playing. You can hear a muted track when you play back the audio file.
4. Solo Button - The Solo button plays only this track (or other solo tracks). No other track will play with the Solo button selected.
5. Gain Control - The Gain
control affects the volume of the track. You can move it left to decrease the volume of the track or to the right to increase it.
6. Panning Slider - The Panning Control affects the balance between the left and right speakers.
7. Vertical Ruler - The vertical ruler is a guide to the levels you see in the waveforms. A level of 1.0 or -1.0 is the maximum supported by the audio-file. Any waveform that goes above 1.0 or below -1.0 will be clipped and will result in distortion.
The mouse turns to a magnifying glass when held over the vertical ruler. By clicking, you can zoom vertically, and be shift clicking, you can zoom back out.
