Mixdown to MP3 gives 32000 hz files

[DCLR-Records]

Hello
Why do I only get 32000 hz MP3 files when mixing down to MP3, even though selecting 44.1 kHz ?
Funny thing is I can not even listen to these files in Pyramix afterwards, since minimum SR is 44.1.

Are you sure it's 32000hz? I've experienced a similar problem when crating Mp-3's. They turned out to be 32 bit instead of 16 bit that I chose. THey can be played back however.

Cheers, Arnoud

DCLR-records, I have some questions in descending order of likelihood, depending on the method you used to create the problem MP3s.

The notion of word length or bit depth is not really applicable to a compression scheme like MP3, so that reading can be disregarded, as they will always show up as 32 bit in Pyramix. The sample RATE, however, is a different matter, and if you are indeed getting 32 kHz. SR mp3 files when you intended to create them at another rate, then there is something wrong somewhere:

Are the MP3s being created as part of the Album Publishing Process? Is it possible that you have mis-configured an output Sample Rate setting in the Publishing set-up pages?

Normally, files output from the Main Menu > Project > Mixdown process will be the same SR as the current Project, unless the "SRC and Re-Dithering" box in the main "Mixdown" window is checked. Was it?

Is Real-time Sampling Rate Conversion turned on in the main Settings > Application > Playback/Record page? Are you using source material that is at different Sample Rates in a way that could somehow confuse Pyramix?

Are you using mixed Media types? I'm thinking of the problems which can result when you are using a mixture of PCM files (.pmf or .wav) and compressed formats (ogg, flac, AAC or mp3) simultaneously on different tracks.

Is Pyramix using its internal clocking, or is it being slaved to an external Sync source?
