project´s bit rate

Isn´t sonar supose to set sampling rate and bit depth of an old project
I try to open?

i.e. If I have sonar set to 24/48 and I open an older project done at 16/44 isn´t sonar
supose to automacticaly change it to the projects res settings???

Thanks

Hello joni,

Hope you're up and running now! All probs solved?

My undersatnding is that the settings you amke under Options->Audio are for new projects only. So, for example, if you set it to 14/48, it won't automatically convert an earlier recording made at 16/44.1 to those settings.

Just to expand, there wouldn't be much point if it did - effectively, all it would do, I believe, is increase file size, not sound quality - beacause you can't effectively up-sample.

If, however, you need to convert an old project from 16/44.1 to say 24/48, just to make it consistent with some other tracks that you're maybe burning to DVD, I guess you could mix it down at 24/48 (though as I say, you wouldn't get true 24/48 sound quality), or use a program like Sound Forge to convert an existing mix.

I hope this makes sense. My brain's a bit fuzzy today!

Cheers.

Hi glazfolk,

Yes, my rig is working really really well mate. Finally. No crashes, no blue screens, and no irq conflicts.

That was not what I meant. Sorry, maybe it is my english.
I just wanted that sonar opened projects recorded at 24/44 at 24/44.
What is happening now is tat the project recorded at 24/44 opens under 24/48 and it plays slower. I wanted that
sonar automactically switched the original sample rate and bit depth of the project.

Was I clear now? My head is also not well this past few days.

best

Yay,good for you djoni

Just a hunch ... have you checked what the EWS88MT Master Clock is set to under the Terratec Control Panel Settings? Try setting it back to 44.1, then reopening Sonar and run the Audio Wave Profiler. Let us know if this is it - I could have the same problem myself one day.

PS I guess your sound card drivers are OK now? Evidently the EWS88MT can use Phase 88 drivers OK.

Cheers.

Just 2 cents here, but Sonar displays the project settings in the lower right on the status bar. You can open othe project and see how Sonar is processing the project. Older projects at different bit rates do seem to be retained in the project.

Most sound cards and drivers will let Sonar do that. However, some will not and you have to change the settings in the sound cards control panel. My old PreSonus firepod was like that, it was a major pain in the @ to change to a project of a different sample rate. It would even crash Sonar if I forgot to do all the steps just right.

Tools - Change audio format might help after opening the project

will try tomorrow in the studio.
All this behaviour is in my latop with builtin audio card.
thanks everyone

What happened with my firepod is that I had to do several things before I could play the project. Because Sonar "checks" the sound card when it starts to make sure it can do the default sample rate you have to go to audio options and change it to the sample rate of the project you want to work on. Then close Sonar. Then open the ASIO panel for your card and change the sample rate to the same value. Then restart Sonar and open the project.

This is not Sonar's fault. A sound interface should let Sonar send it a message to change the sample rate clock and most cards respond to this message just fine so you don't even know that it has happened. However, interfaces with bad drivers ignore this message and will not send a message back to Sonar that the clock has been set correctly. My old Firepod was exactly like that, it would not respond to Sonar. However, my new Lynx Two card does and works perfectly. I can open a project of any sample rate no matter what the default in Sonar is set for and it just works. That's as it should be.

Not knowing the charactersistics of the built in card I don't know, but it might be worth under Optrions->Audio experimenting with the Driver Bit Depth settings. Try it at both 16 and 24 - see if this helps.

Cool Edit would do this too from time to time. If you set the default in the audio options to 24/44.1 with no project open, and then open the existing project, I think that will fix the issue.
