I have been asked to convert a wav file in an obscure format to something more friendly - like an audio file that can be played in most standard players under XP.
I have used Gspot to try and identify the files and it reports that the codec is 0x0120 (PHILIPS CELP), 8000Hz 19 kb/s (1 chnl) I have looked everywhere for a codec, and failed. I have downloaded many utilities and converters - none will work. The files were made on some dictation system - Philips I think. I know I am probably dealing with proprietary architechture here - and Philips only want their files to work with their kit..... Any ideas? Many thanks |

The Philips MPEG 4 player available halfway down http://rarewares.org/mp4.html might play them. Some other MPEG4 capable players might also play them. The problem is going to be if the files are in some non-standard or proprietary container format instead of the MPEG standard one. |

I think you might be right about the container. |

If you find a way to re-package it to MPEG-4 you may have a chance with MPEG-4 enabled players like QuickTime.

I used a Philips SDK for decoding. I note that I have a codec named smcelp.acm. The Philips SDK wrapped calls to the codec in some simpler calls to one of their DLLs. Alan Lloyd |
