I’m using Audacity 2.0.5, on Windows 7. I have made a recording of an interview (i.e. it is voices only not instruments). I made the recording on a ZOOM H4N recorder. The interviewee was speaking into an external microphone, I was speaking into the inbuilt microphones, I recorded it in ‘stereo mode’ as a wave file.
I think I made a mistake in setting recording levels when recording, because what I get when opening it in Audacity is two tracks with tiny, tiny squiggles, and the sound is very faint. The playback meter doesn’t seem to get much above -24 and at times hovers around -36. However if I slide the ‘track gain slider’ up, the volume is ok. I tried doing that and saving the file, and that worked, however there are sections of the recording e.g. the first 30 seconds specifically, which seemed to have recorded at a decent input volume, so that section is extremely loud and distorted in the new saved file. I have identified several sections of the recording and the differing volume gain that I want to apply to each section(varying between +5 and +25) , however I don’t know how to apply the gain to different sections and save it. Can anyone help?
By the way, I did try the Amplify effect and it didn’t seem to do anything (I left it on the default values) and I also tried the Compressor effect, and it did improve the volume, but not enough. Also, my voice on the inbuilt microphones is fainter than the interviewees voice, but I don’t care about that – i.e. I don’t need to isolate the different tracks and apply different volume gain to them, I want to just make both tracks equally more loud. Any help much appreciated.
