ive got truespeech data which i need to play with naudio.

96 bytes of data is to be played on an interval of 85 ms. how do i accomplish this?


MemoryStream ms = new MemoryStream(Encoding.Default.GetBytes(truepeechdata));

RawSourceWaveStream rws = new RawSourceWaveStream(ms, WaveFormat.CreateMuLawFormat(8000, 1));            WaveFormatConversionStream pcmStream = (WaveFormatConversionStream)WaveFormatConversionStream.CreatePcmStream(rws); 

 WaveOut wo = new WaveOut(this.Handle); 




something like this produce a tick sound..

you are marking your rawsourcewavestream as being mulaw, but if it is truespeech, then you will need to pass in the correct WaveFormat. Use the TrueSpeechWaveFormat class instead.

i used the truespeechwaveformat class and the sound is playing but its too much breaking in between.


TrueSpeechWaveFormat tspf = new TrueSpeechWaveFormat();

WaveOut wo = new WaveOut(this.Handle);

MemoryStream ms = new MemoryStream(Encoding.Default.GetBytes(dataToPlay));

RawSourceWaveStream rws = new RawSourceWaveStream(ms, tspf);      

 WaveFormatConversionStream pcmStream = (WaveFormatConversionStream)WaveFormatConversionStream.CreatePcmStream(rws);   




do i need to change any truespeech format? bits per second or anything?
