Hey everyone -

I have a .wav file that's in 48kHz, 24-bit, stereo format and I need to downsample it to 11.025kHz, 16-bit, mono.

The problem w/resampling (in Sound Forge) is that the pitch changes. I just want the crappier sound quality with the same pitch (this is voice-over stuff). How can I do that and with what tool?

Thanks...

Wavelab will do, I know that for sure. Kind of surprised that Soundforge won't do it right; are you sure that you aren't changing the playback rate instead of resampling?

I believe so. I select 'Resample' from the menu and set the new sampling rate to '11025.' I then click on the 'Preview' and the audio has totally different pitch. Maybe I'm not using this correctly?

Anyone?

Just a big guess here.. Is you soundcard set to 48khz?
Im thinking of that if you play an 11khz wavfile in cubase and the project is set to 48khz, the playbackspeed will be wrong of the file.

I'm not in Cubase. I just resample the file, save it, and re-open it in Sound Forge. I don't know if Sound Forge has a global sample rate...

I'll look...

Hi,

You should make sure that you have NOT checked the setting: "Set the samplerate only". This should be off.

EDIT: This is an option that appears in the resampling-box in SoundForge.

Hope it helps.

That setting is off. I actually toggled it both ways with bad results both ways...

Ok...I just learned that it works fine on my desktop DAW w/a Delta 1010, but my laptop still can't do it. It has an Echo Indigo -- can anyone else verify this? Is there something with their driver or a setting that I am missing?

Thanks everyone...

SF 7.0 - should be Process->Resample, Be sure that "Set the Sample..." is NOT selected.

Off the top of my head, sounds like the Delta can do 11k, but the Indigo can't.

Open you ECHO console and under settings, driver, lock your rate to something like 44100 Hz and try to play the sound.

The ECHO console only gives buffer settings and allows you to select ASIO 2 direct monitoring...nothing about sample rates...bummer...

Yup...good call...

I just found the detailed specs and the Indigo can only go down to 32kHz!

I'll stick w/the Delta for this stuff...

Thanks to everyone...

Looks like you haven't updated your drivers. Console3 should allow you to select and lock the sample rate. I checked Google and looked identical to latest ECHO console.

Just to verify, I generated a test tone, saved as 11Khz WAV and played flawlessly in Media Player 9.

Dumb downsampling question...
