Greetings. I have just begun using Audacity and so far like it very much.
I have audio voice tapes (interviews) that were originally recorded at a slow recording rate of 2.4cm. When I digitize them using Audacity they playback at a faster rate. Is there a way to change the tape speed on Audacity?
Thank you.
Greetings, Gale, thank you for responding.
I am using a device purchased online that came bundled with Audacity. It connects to the computer via USB.
The first recording of music I copied worked perfectly. The second tape of an interview is copying at a fast speed and the speaker sounds like a chipmunk. Both the music and the interview were recorded on the same device. The music was recorded at 4.8cm and the interview was recorded at 2.4cm.
The third tape, professionally recorded of a man giving a lecture, is working perfectly.
Please accept my apology. I am not accustomed to using this forum and did not realize that responses to posts were held for approval. When I did not see my first response to Gale I thought I had forgotten to post it so I wrote a second. They both address the same issue. This won’t occur again now that I know there is a lag time between posting and viewing. 
No problem, I deleted the duplicate post. In due course you will no longer require approval as long as your posts are legitimate and not advertising something for sale.
Does the interview play at the correct speed on the device? If it does, then perhaps you will need to be more careful about the project rate you choose bottom left of Audacity.
Right-click over the speaker icon by the system clock, then choose “Recording Devices”. Right-click over the USB device choose “Properties”. Then click the “Advanced” tab and observe what sample rate “Default format” is set to. Set Audacity project rate to the rate observed in Default Format, and use MME “host” in Audacity’s Device Toolbar.
Or don’t use 2.4cm recording if you can avoid it, or use Change Speed afterwards.
