Move Track Up - exchange places with the track above this one.
Move Track Down - exchange places with the track below this one.
Waveform - sets the display to Waveform - this is the default way of visualizing audio.
Waveform (dB) - similar to Waveform, but on a logarithmic scale, measured in decibels (dB).
Spectrum - displays the track as a spectrogram, showing the amount of energy in different
frequency bands.
Pitch (EAC) - highlights the contour of the fundamental frequency (musical pitch) of the audio, using
the Enhanced Autocorrelation (EAC) algorithm.
Mono - makes this track a mono track, meaning it is played out of just one speaker, or played out of
the left and right speakers equally.
Left Channel - makes this track come out of only the left speaker.
Right Channel - makes this track come out of only the right speaker.
Make Stereo Track - if there is another track below this one, it joins them to make a single stereo
track, with the top track representing the left speaker, and the bottom track representing the right
speaker. When tracks are joined into a stereo pair, all edits automatically apply to both the left and
right channel.
Split Stereo Track - if the selected track is a stereo track (a pair of left and right tracks joined
together as a single track), this operation splits them into two separate tracks that you can modify
and edit independently.
Set Sample Format - this determines the quality of the audio data and the amount of space it takes
up. 16-bit is the quality used by audio CDs and is the minimum quality that Audacity uses internally
(8-bit audio files are automatically converted when you open them). 24-bit is used in higher-end
audio hardware. 32-bit float is the highest quality that Audacity supports, and it is recommended
that you use 32-bit float unless you have a slow computer or are running out of disk space.
Set Rate - sets the number of samples per second of the track. 44100 Hz is used by audio CDs. Tracks
can have different sample rates in Audacity; they are automatically resampled to the project sample
rate (in the lower-left corner of the window).
[MENU]
File Menu
New - creates a new empty window
Open... - opens an audio file or an Audacity project in a new window (unless the current window is
empty). To add audio files to an existing project window, use one of the Import commands in the
Project menu.
