Spectro-Edit 0.4 (Default branch)

Spectro-Edit reads in regular PCM audio files, then shows the audio visually in a time vs. frequency plot. The fun part is that you can "paint out" any part of the visualization and play back the audio subject to your modifications. When you are happy with the result, you can save your work back to a WAV file. This could be useful for podcasting (edit out microphone noise, chair squeaks, phones ringing, and other background noise), music (make strange and unusual modifications to the sound for artistic reasons), research (visualize animal calls or noise pollution from nearby industrial activity), and general purpose geekery (which was the original purpose). License: GNU General Public License v3 Changes:
New features include: improved visualization with more user control, and optional use of colour to double the displayed value resolution; exponential sliders, which greatly improves their useful range; the cursor position readout now shows the nearest musical note name (to the semitone); repositioning of playback by clicking in the header; and the ability to load stereo samples (they are automatically mixed down to mono). Bugfixes include elimination of the audible blip at the end of the clip, and numerous small but noticeable improvements to the shuttle controls and the rest of the GUI.

play(1) 						      General Commands Manual							   play(1)

NAME

       play - play any sound file to audio device

       rec  - record audio to any sound file format

SYNOPSIS

       play [fopts] infile [effect]

       rec [fopts] outfile [effect]

DESCRIPTION

       This manual page briefly documents the play and rec commands.

       play  and  rec are programs that allow you to play and record different types of sound files from the command line.  They are front ends to
       the more general sox(1) package.  Normally, the play command will automatically detect the type and other parameters of the  soundfile.	If
       it can't do so, the parameters can be changed through options.

OPTIONS

       A summary of common options are included below.	For a complete description of options and their values, see the sox(1) man page.

       -c [channels], --channels=[channels]
	      Define the number of channels in the file.
