I am recording some scratch piano songs I made on an Olympus mono voice recorder to Audacity so I have a back up. I have the following settings:
Audio Host:MME
Recording Device: Microsoft Sound Mapper - Input
Recording Channels: 2 (Stereo) Recording Channels
Playback Device: Speakers (Realtek High Defintion)
When I put it in record mode and on pause, and play the Olympus to adjust the volume etc., I can hear and see in the meters, a pulsating low frequency sound. It can be heard in the recordings too. The sound is like a bup bup bup bup bup bup bup bup…
I have the recording volume adjusted pretty well below 0 db.
I do not hear this sound when listening directly to the Olympus.
Does anyone know why this is happening? Please let me know how I can get rid of this sound.
Thanks!

I bet a lot of chocolate that’s feedback. The recorder is not recording the clean show. The recorder is recording it’s own monitor feed, or its feedthrough confidence connection.
I’m guessing it only does that when everything is connected and running. If you take it all apart, suddenly everything works perfectly.
I would have to build your setup in my head and I haven’t got enough Starbucks yet.

How they connected? (We don’t know what’s getting “mapped”.)
Does your Olympus have a USB connection?
I think I see where this is going. My Olympus recorders will hand me a sound file.
No juggling with sound pathways or volume and feedback problems.
I think all of mine have USB of some sort.

Still in active use.
That’s been a while. It’s more normal now to have a tiny female USB connection around somewhere. Even my newer computer which doesn’t have regular USB, has a connection to an adapter which does.

Even if you do everything right, it’s still possible to dig yourself a hole. This model was chosen because it will save my sound work in either efficient, space-saving, compressed MP3, or perfect quality, Windows Media, (WAV).
You might say who cares if my voice clips are large, and taking a bunch of memory space? You might if one of your voice jobs is difficult and low volume. MP3 plays tricks to get the small files. They carefully re-arrange voice tones and hope you don’t notice, and in some cases, just leaves them out.
MP3 was designed so you can fit a lot of songs on your player while you run on the beach. It’s not a valuable editing and production format.
