how can i open this creepy file?
uncompressed 8-bit PCM mono samplerate 11025 bitrate n/a
i tried some -raw parameters with soundfiler and get the pitch but still sounds very noisy
sorry , i forgot [PD] on the title... i'm in a hurry :S

hmm, [PD] is automatically added by the listserver, you don't have toworry about that....

for one thing, an 8bit PCM file will always sound very noisy :-)
nevertheless:
- i don't think you can open 8bit (1byte) files with soundfiler,
readsf~ or the like. (at least, after reading the code, i don't think you can).
- [soundfiler] and friends are sample-rate agnostic, meaning that they
will straighforward ignore whatever samplerate the soundfile claims to have. however, you can speed up (or slow down) the playback speed by using [tabread4~] instead of [tabplay~]
but because of problem#1 i suggest you pipe your soundfiles through sox before trying to open them in Pd.

Depends on how well the original file is using the range it has. You don't use plain 8-bit PCM to represent both loud sounds and quiet sounds, because e.g. if a certain quiet sound has 1/32 of the amplitude of a fully loud sound, then it's using only 3 bits instead of 8 bits...
Using too few bits introduces a lot of noise, but this depends on the interpolation being used. If you convert it from 11025 to 44100 the obvious way, you'll get a lot of very-high-pitched noise. Applying a low-pass filter like [lop~] (or several of them) can get you something similar to having used interpolation.
Perhaps you are actually not reading the file using the correct specs, but you don't give us any way to verify that.
