Revision history for Perl extension Audio::DSP. 0.01 Tue Aug 10 18:11:57 1999 - original version; created by h2xs 1.18 0.02 Mon Sep 11 00:00:00 2000 - added several new methods: - Opening/closing device - open - Direct read/write to device - dread - dwrite - I/O Control - channels - setduplex - setfmt - speed - The following methods are now deprecated: - getformat - queryformat - setchannels - setdevice - setformat - setrate - The following sample-format constants are now exported on use: - AFMT_MU_LAW - AFMT_A_LAW - AFMT_IMA_ADPCM - AFMT_U8 - AFMT_S16_LE - AFMT_S16_BE - AFMT_S8 - AFMT_U16_LE - AFMT_U16_BE - AFMT_MPEG Consequently, the 'format' parameter in the init() method should be passed in constant rather than string form (string form is deprecated). On a similar note, the open flag should be passed as a Fcntl.pm constant rather than a string (also deprecated).
