Audio sample rate problem

(1/3) > >>

aliciaviola:
If I am using Mediacenter (newest build/ Macbook Pro 2021 M1 Pro/ OS 12.3.1) together with an audio editor like WaveLab Pro oder iZotope RX 9 and play a file with a sample rate of 44 kHz and then a different file in MC with 48 kHz the file in MC sounds a halftone flat. With 96 kHz it sounds like slow-motion.
Is there any possibility to use them without this effect. I often use them simultaneously to compare the pitch of recordings or to make tracks in WaveLab.

Are you enabling exclusive access in MC's audio settings?

You can get detailed information about the audio device opening in MC by turning on logging.
If you do that and capture a log, post it here.

Exclusive access is the option to listen to music in the best possible way and I often use it.
But when I want to work with other sound programs, also, it's impossible to choose this option
because I couldn't work with WaveLab or iZotope in an acceptable way.

It seems like somehow your other programs are changing the sample rate for the device. I'm not sure how this can be but if you pull a log when you duplicate the issue and post it here we can take a look at and see if something can be done.

This has been happening to me for many years.  It usually happens when I play a YouTube video and YouTube/MacOS sets my audio device to 48kHz.  When I then use MC to play a 44.1kHz file, it sounds way slow and low pitched, because it's being played at 48kHz, instead of 44.1.

Generally, the "fix" for me is to press STOP on MC, which seems to reset things.  I generally never use the stop key.  Instead I use the Play/Pause key.  I see no reason to use stop.  I think this is why MC is not setting the sample rate.  MC thinks it set the sample rate at the beginning of the song, so it doesn't bother to reset it when I "unpause" a paused track.  But this track has been paused for minutes, hours, or days, and another program has reset the sample rate while MC was paused.

I guess one possible fix would be to reset the sample rate on every unpause event.

Brian.
