For a few days, all recordings were fine. Today I recorded some piano music the same way I recorded others past few days. But when I pressed the play button, the recording was “unlistenable” - it sounded like it was 10-25 times faster than what was performed!! I didn’t change recording speed or playback speed.
This is my setup - an Audio Technica 2035 mic connected to a Scarlett 2i2 connected to my Dell PC (windows 10), with Audacity as my recording software.
I have no idea what went wrong. Can someone advise?
Speed errors with external audio devices are almost always due to sample rates being different in different places, so check that first.
As diagnosis, if you use Effect > Change Speed…, slow it down by using a negative percent change then listen, is the recording complete, or are there pieces missing?
Are you append recording (SHIFT + R or SHIFT-click the Record button) into the same track? If you do that you must not change the project rate or the track sample rate. If you do change them, the recording will be too fast or too slow (it’s an Audacity bug).
