Toobz is not right. And neither are you at least as far as this argument goes.

Change the sample rate as a value in the wav header, and you change the speed and pitch of playback. Period. Argue all you want, but this is a fact. If you record samples at one sample rate and then play back the same samples at a different sample rate, speed and pitch are indeed affected.

This is 110% correct because this is exactly what was happening to me. The pitch changed (obviously) then last night when I put a metronome in my recording, and then checked it against a realtime metronome (same one), the recording was being sped up at the 22.050 sample rate as opposed to the realtime rate (which should be 44.1).

Well, with each of my sequencing software, I can record and play back at any sample rate I want, and it never changes the pitch because the software looks into the file and detects the sample rate. In this case the software must have _assumed_ a certain sample rate and played it back at the rate. The software didn't do the conversion properly (which it should have) because its was locked into a certain clock speed.

Of course you can, unless you record at one sample rate and play the recorded samples back at a different sample rate, in which case the pitch and speed get munged up. Instead of continuing to insist that this is not the case, why don't you just try it? If you don't know how, I can tell you.

I've had the exact same problem as the original poster, and probably said the exact same four-letter words he did as I tried to figure it out. I knew it was something inside the system becasue both my MIDI keyboards and my sax were suddenly out of tune. I finally figured out it was a difference in recorded sample rate and the current playback rates.

For those who insist playback sample rate doesn't affect pitch/tempo...if you get a chance download the RME Fireface 800 manual, if you don't own one. On page 17, the manual describies the FF800's Direct Digital Synthesizer (DDS), which is a fancy way of describing its word clock.

To make a long story short, RME reccomends changing pitch and tempo by changing the sample rate. Direct quotes from the manual: "DDS allows for a simultaneous change of speed and tune during record or playback...DDS allows to intentionally detune the complete DAW (sic)...DDS allows to define a specific sample rate (sic)."

The FF800 allows you to tune the sample rate in small increments. If you mess with that, you'll still get playback...but it will be out of tune. On my system, plug in sysnths like Trilogy and B-4 will play out of tune even if you're not recording.

That word and several others as well, actually, lol.

Guys, unfortunately it happened to me too - that's how i found this thread - i've been in google searching for "audition recorded pitch changed". Unfortunately i lost a day's of hard work since the audio file is totally out of tune. I don't know the why's ... if it was sample rate or not (as i tried recording 48k and i got some slight noise pops and then switched back to 44.1) or whatever. What matters is that it happened. Next time i am definitely using reaper or any other daw for recording. I am so scared of this happening to me again.
My laptop is 4th generation i5 with SSD. I've been recording straight from MIXER USB (qx1202usb) using ASIO I/O

What software are you using? What interface?

I think I've encountered every possible issue with desktop recording, but never that one-

I've been doing digital recording for 15 years and using Protools almost exclusively since 2004 and have never had a single recording change pitch unless I told it to.
