WAV- or + AU-file headers are ignored if this flag is set. + +Version 0.4.1, 3.5.1997: + + - sun header gives odd aligned starting point + for sample. temporary fix. + + - read_big_endian_long returned wrong value if + sampling rate was 44100. this caused tplay + not to work with that speed when playing sun + audio or wav file. fixed now. + +Version 0.4.2, 7.5.1997: + + - read_big_endian_long and similar functions: + parameter's type was char* and that was a bug. + changed to byte* (unsigned char *). conversion + should also be saner now. + + - force playing -f (or --force) flag added. this + makes tplay to ignore sound driver's results + when changing parameters. + +Version 0.4.3, 12.5.1997: + + - binary is statically linked to LinuxThreads + version 0.6 now. + + - print sun header comment if verbose is requested. + + - sun audio file's data stream starting pointer + is read and set from the header. + + - to avoid rounding errors when playing 16bit + and/or stereo (au or wav) sample, data section + is moved now to the beginning of buffer before + playing. + +Version 0.5, 23.10.1997: + + - set_audio_parameters() partly rewritten and + changes to open_audio(). + + - in some WAV-files, data-portion is not started + with 'data'-magic but 'INFO' instead. some + players don't even check that so tplay prints + just a warning message now if neither of these + magics exists. + +Version 0.5.1, 25.10.1997: + + - printing of buffer usage changed from producer + to consumer. this makes this silly feature a bit + more informative as it is still active after the + producer has stopped. underflow situation (when + the big buffer needs to be refilled) is also + possible to show now. + +Version 0.5.2, 9.5.1998: + + - Jerko Golubovic <jerko.golubovic@public.srce.hr> + kindly modified the code to support those soundcards + that may result slightly different sampling rate + than requested. he also provided RPM of tplay. + + - added -D (or --device=DEVICE) flag for setting + audio device to be used. + + - added feature to -B (or --buffer-size=SIZE) flag. + buffer size can be given in seconds now, too. + +Version 0.5.3, 11.5.1998: + + - rewrite of playing routine to support multiple + sound samples from command line. + +Version 0.5.4, 19.5.1998: + + - added -l (or --loop) flag to support looping sound + samples. + + - sun port. + +Version 0.5.5, 24.5.1998: + + - added environment variable TPLAYDEV, which sets the + audio device to be used. decoding of command line + options is moved from main() to another function. |
