I spent several hours looking for an answer to this issue in various parts of the internet as well as this forum, and while I found a few issues that were somewhat similar, I wasn’t able to locate anything relating to my specific problem.
I’ve been using Audacity 2.0.5 for about a month now and I think its amazing software. It’s been working absolutely fine for me ever since I began with it, but, while recording an audio segment for a video project this past Saturday using a conventional microphone, I found one of the files horribly distorted. The first clue that something was wrong was that the waveform in the topmost track was missing. (This has actually happened before, but I thought very little of it because usually the audio still works and if I truly need the waveform exporting the file out and back in as an MP3 usually brings it up) When I tried to playback the audio, it was extremely quiet, I had to Amplify it up to 40 dB to be able to hear it at a normal level, (at which point the waveform appears) but when I am able to hear it, the tempo was drastically increased. (By about 40% the piece that was supposed to be 52 minutes long is currently 31 minutes) I was able to fix the tempo with the Change Tempo effect, but now the audio sounds very echo-y, like I recorded it in a fish tank. I recorded two other pieces of audio that night after this one and they both work fine, its only this single, solitary file I’ve ever had an issue with. I had a USB webcam recording simultaneously with audacity, and the audio from the webcam doesn’t have this problem. (It just sounds like garbage, cuz, ya know, webcam) From my research this seems to be indicative of an issue with the sound card, but, to be frank, I don’t have one. The computer I record on is a workstation that runs on integrated audio, and furthermore, if it was a hardware issue, why would it work perfectly for a month, screw up once, and then go right back to working perfectly?
The audio on that file represents a very important segment I am loathe to lose. Can anything be done to salvage it? And are there any steps I can take to ensure this doesn’t happen again?
Thank you for your time.
