I have been using Audacity for years. I am now trying v4 and have run into an odd, periodic buzz (sounds like a bee or mosquito). You can hear it at the 8 sec. mark in the sample below. (it is faint; you may have to crank up your volume to hear it)
This does not and has never occurred for me in earlier versions. There has been no hardware or software change; everything identical, including the recording specs between v3 and 4.
PS: The infuriating implementation in v4 of making a selection and playing it may be a deal-breaker for me. There seems to be no way to isolate it so only the selection plays. PLEASE make it as it was in v3!
The sound seems to overlap the speaking–not to mention that the first few seconds of the longer clip included below contains the sound before I even speak.
Again, this has never occurred in v3, even today testing it in v3 just after it occurred in v4. All settings are identical to those I have used in earlier versions for quite a long time. I record my notes every week. There has been no Windows update since last week, using v3. The only thing that is different is that I am using v4.
I confess that you have now lost me. I am unable to duplicate your screen shot, and every time I view the Amplify dialogue–either in v3 or v4, whether in the original file or the MP3–I do not see “-infinity”, but the typical “0dB”. Questions:
How could I have accidentally “applied a noise-gate”?
Can you explain “not a raw recording”? (I just recorded the same as I do every week without incident.)
