create waveform sawtooth
...requencies result in longer waves. But that?s not all: as frequencies increase, it appears that wavelengths increase to infinite length, then get shorter again as the wave reverses, then it gets longer and flips again.
Here?s a small file that demonstrates the bad sawtooth waves:
library(tuneR)
sample_rate <- 12000
reverse <- FALSE
mycolors=c("red","orange","yellow","green","cyan","blue","violet","magenta")

create waveform sawtooth
Ccing the maintainer if the tuneR package.
Looks to me like sawtooth (and square) don't behave as expected when using xunit="samples". Workaround is to use xunit="time" instead:
sawtooth(110,duration=1/100,samp.rate=sample_rate,xunit="time")
I looked at the code but found it to be opaque.

thanks
I received this bug report from a Debian user. I can't think of any reason
offhand why the command line tool would work while the xmms plugin would
fail.

Speex in flash player: how to work with?
Nicer way:
void* speexState = speex_encoder_init(&speex_wb_mode);

speex_encoder_ctl(speexState, SPEEX_GET_FRAME_SIZE, &speexFrameSize);
speex_encoder_ctl(speexState, SPEEX_GET_SAMPLING_RATE, &speexRate);
SpeexPreprocessState* speexPreprocessState = speex_preprocess_state_init(speexFrameSize, speexRate);
