Playback Volume Drift

blueranger

Hope someone has encountered this prob before.

I record streamed radio plays (vocal & ambient sound), since installing wavepad & associated programs the playback volume of the recording fades up and down in volume.

I record mpeg1 layer3 160kbps joint stereo with automatic gain controls turned off ( but have been on as well). I'm using:- Sound Card C-MEDIA sound device & Recording Device WAVE.

To record: tried both RecordPad and Audio Recorder for Free v5.6.

Previously used AR4Free before installing Wavepad and had not had this problem.

I've tried many variations of settings but still end up with the volume drift.

I'd be very grateful for any advice as wavepad seems a very usable program.

Regards

By "volume drift," are you talking about a "pumping" up and down of the volume in between louder and softer portions of your recording, as if some sort of automatic level control was active during the recording process?

If yes, then I'm experiencing the same thing. When I make a recording with Wavepad and listen to it, I can hear "pumping" of the volume level, and it's clearly not the playback that's doing it, but rather something in the recording process, and not something that's desireable.

I can't find anything in the NCH Wavepad FAQ about this, nor anything in the program's Help about it either...but maybe I'm not looking hard enough.

BTW, I'm not using any of the advanced settings while recording, and I've experienced this both with the current and with older versions of Wavepad. It has nothing to do with AGC, which is an effect applied to an existing recording...it's happening during the recording process, and I don't understand why, because the sound source itself (MP3, or audio stream off the web, CD playback, or whatever) doesn't have the volume pumping.

Thanks in advance for any help.

Hmmm...I posted this back in April and was really hoping someone might be able to help. I just recorded a song that was playing on my PC and when I played it back, there was pumping up and down of the sound level. Am I doing something wrong? Is this a "feature" of WavePad?

I will throw my hat into the ring also. I have the same issue, and hope to see some meaningful comments? I have been experimenting, but have not found the answer yet - not sure what to try ...

I am experiencing the same issue. The volume unexpectedly fluctuates during playback. When it becomes quieter it sounds like there is flange on the track. Then it returns to normal sound, only to get quiet and flanged out about 5 seconds later. I have repeatedly tried to make sure no effects are turned on. That doesn't seem to be the issue. It seems to be something with the software. IT's as though it is preset to record with volume fluctuations and flange.

Somebody please help...........is the software supposed to operate this way?

You need to go to the advance record options in the record control window and uncheck the auto trim recording option.
