Re: Problem with recording at 2X speed

Hi,

Please can you confirm, if you connect your headphones to your Scarlett's headphone output, turn on direct monitor and mute any sounds from software, is the playback speed still fast?

Doing this bypasses any software problems and routes the inputs directly to the headphones output.

If the problem is still there then I'd suggest the issue is earlier in the chain, at the record player.

Please can you check what speed the record needs to be at (probably 33 1/3 RPM) and set your turntable to match this.

As the sound is speeded up, it sounds as though you may be using a faster speed, 45RPM or higher, when the album needs to be at a lower speed.

Thanks,

Ed

Check the turntable speed as Focusrite suggested.

Set your Audacity project rate bottom left to 44100 Hz If the Scarlett is set to a 44100 Hz 16-bit choice.

Please look at these questions:

It makes a difference as to which driver you use, but my understanding is that you should follow the instructions in the manual that came with 2i2 to install Scarlett's own drivers. Using Windows generic USB Audio drivers could easily cause a speed problem even if all settings are matched to the same sample rate.

If you have lost the manual or any drivers CD you had, you can obtain them from Focusrite:

Something else you can try - Try all 3 Audio Host options. (Maybe one of them is having driver compatibility problems.)

And if that doesn't help... Does it play back too fast in Audacity immediately after recording, before exporting? I would assume so.... I wouldn't expect anything to go wrong during export, but this is an unusual problem and something unusual is going on...

...Its also possible that the Scarlett is flaky. If you have a desktop computer with a regular soundcard, try the line inputs. If you've got a laptop, try the built-in mic. (If those work OK, it won't tell you if it's hardware or drivers but it will confirm that it's a Scarlett related issue.)

I solved the issue but can't explain how. The Scarlett was set for 16-bit 44100 hertz and Audacity was set for 24-bit 44100 Hz. I put them both at 96k and it worked fine. I lowered the Audacity back to 44100 and it worked fine. Then I lowered them both back to 44100 and it works fine. No clue what happened but as a slap upside the head, it worked. Not an elegant solution but I'll take it. Thanks to all for your input. sh

I'm glad you solved it, but it still seems like you are saying that the Scarlett is unpredictable. If it happens again, come back to this topic and look at all the suggestions made here, including drivers and Audacity Audio Host.

Remember to cold boot regularly. Windows button, Power button then hold SHIFT on your keyboard and click "Shut Down". Not doing this can cause just about any kind of problem with a USB device.

I think it comes down to confirming the speed every time you load the program. The speed shows the same but maybe it doesn't really believe it until you pat it on the head. Thanks for you help, sh

As I said, there should not be that kind of variability. We have outlined the steps you can take which are founded on much experience helping users with similar problems.

Not Audacity -- the driver for the Scarlett.
