Yes I do. When I select either of the 32 bit options in that pulldown, the volume of my wav file goes to 100% (see lower screen capture above containing large block of blue).

Thanks. I reset my preferences and the 32 bit option works now. I appreciate the help.

I did a reset and it solved the problem for a while, but 2 weeks later the problem started happening again.

@David-Rees Which audio driver is selected in the program preferences? Usually, Microsoft Sound Mapper should work fine, in case this is caused by the audio driver.

Microsoft Sound Mapper. I contacted Magix support a month ago using their support ticket form. I received an email saying some error occurred with the form and they asked me to resend all my information in an email (which I did). I haven't heard from them since.

@David-Rees Does this problem happen with any WAV file? For example, if you create a new file and fill it with the noise generator, does changing the bit depth also cause the volume to deteriorate? If other files aren't effected, maybe it has something to do with the files you're trying to edit. Are these standard PCM WAV files?

Yes, it does happen on a new file I create - but this helped illuminate something: It only happens when I am lowering the bit depth to 32.

Steps:

1) Create new 44-16 stereo file

2) Change bit depth to 64

3) Change bit depth to 32

Problem happens

Can anyone else duplicate this when going from 64 to 32bit?

@David-Rees

Hi

I can replicate this using the steps you have given, however it does beg the question why are you doing this?

Increasing the bit depth from 16 to 24, 32 or 64 bit does not gain anything in dynamic range or compensate for editing losses.

The reverse is actually used in professional recording, and editing, ie starting with the higher bit depth eg 32 or 64 for recording and then, for final product, convert down to the required bit depth where required.

However the actual bit depth you can record at depends on the audio device Microsoft Sound Mapper is using, this is normally the Windows default recording/playback device which, by default, is the Windows Stereo Mixer which does not support 32 or 64 bit for recording.

Thanks John. This client had me doing a bunch of work that involved pitch and time stretching audio that they recorded on their end. My general procedure before I use algorithms to manipulate audio like this is to upscale the audio, perform the functions I need to perform (on higher sample rate and bit-depth audio) and then downscale the final result to the spec they want for delivery.
