Go on, it's easy! http://uk2.php.net/manual/en/function.exec.php That said, depending on your hosting, you may be banned from exec. > For the moment, I can use a HEX Editor and inspect the first 256 bytes > of a wav file and find out all the goodies therein, but do you know if I > strip out the first 256 bytes can I then combine the files so they will > work (providing the sample rates, frequencies, and such as the same)? No need for a hex editor... 1) Take all your .wav files and use sox on command line (or another tool if you prefer) to convert them all to RAW PCM files (e.g. no header). 2) Take the filesize of the WAV and subtract the filesize of the RAW PCM. The value you have left is the size of the WAV header, so take the first n bytes of one of your WAVs and save it to e.g. "wav.hdr". Double check with your hex editor as I'm not 100% sure about this (OK, you do need it after all :p) 3) In theory to create the full wav you just concatenate the wav.hdr + the correct combination of your letters/numbers RAW PCM files. 4) You should be left with a proper, valid .wav file (I think). Not really sure of the above but I think it's all true!! Take care. Col. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
