NAME="History"></A> +<H1><B>History</B></H1> +<P> + My first attempt at reading and writing WAV files was in 1990 or so under Windows + 3.1. + I started using Linux in early 1995 and contributed some code to the + <A HREF="http://www.vaxxine.com/ve3wwg/gnuwave.html">wavplay</A> + program. + That contributed code would eventually mutate into this library. + As one of my interests is Digital Signal Processing (DSP) I decided that as well as + reading data from an audio file in the native format (typically 16 bit short integers) + it would also be useful to be able to have the library do the conversion to floating + point numbers for DSP applications. + It then dawned on me that whatever file format (anything from 8 bit unsigned chars, + to 32 bit floating point numbers) the library should be able to convert the data to + whatever format the library user wishes to use it in. + For example, in a sound playback program, the library caller typically wants the sound + data in 16 bit short integers to dump into a sound card even though the data in the + file may be 32 bit floating point numbers (ie Microsoft's WAVE_FORMAT_IEEE_FLOAT + format). + Another example would be someone doing speech recognition research who has recorded + some speech as a 16 bit WAV file but wants to process it as double precision floating + point numbers. +</P> +<P> + Here is the release history for
