Welcome to AudioTools

AudioTools is a lightweight audio manipulation toolbox.

The core of the audio tools is a filtered-pipe/stream mechanism. The pipe streams audio data, either as time-sampled audio data (PCM) or as frequency samples (blocks of fourier coefficients). As a programmer, you hook up the source (file, microphone) and sink (speaker, file), insert and set the required filters, and you start the streaming.

As an end user, you can simply run one of the applications

The main components are

component	function	docu
pipe	basic definitions for audio pipe
audiofilter	The audio filters to be applied to the streams
audiogui	A basic GUI that shows users a text to pronounce, records the audio and then user can drag sliders to modify the way it sounds	audiogui/doc/audiogui.pdf​
audioconverter	Converts bunch of files according to settings
trimtool	Trims audio according to noise threshold settings	trimtool/doc
