Win7 revert, Record in mono

[edwinn]

Hello, I've updated to 2.4.2 without knowing it may not be compatible with Win7-64. Had a few issues since updating.

1) Resampling audio to lower freq changes the Tempo of the audio to higher pitch. Several down-sampled files were made without knowing what was happening.
2) Caching while applying an Effect or exporting is slower and choppy.

Part 2
What's the best way to revert? install over 2.4.2? I'm perfectly ok with going back a version or two.

Part 3
I'd like to record Mono radio shows in MONO, but cannot figure how to set that up, or find the correct keyword to search HELP.

Thx

1) Resampling audio to lower freq changes the Tempo of the audio to higher pitch.

If you want your exported file to be at a different sample rate, do not resample. All you need to do is to set the "Project Rate" (lower left corner of the main Audacity window) to the sample rate that you want the exported file to be.

2) Caching while applying an Effect

What do you mean by "caching"?

I'd like to record Mono radio shows in MONO

Set the "number of channels" in the Device Toolbar to "1 (mono) Recording Channels".

Yes you can do that, but be sure to "Reset Preferences" during the installation. However, I suspect that the problems that you have reported are not caused by the later Audacity version.

That shouldn't be happening and I can't imagine the Windows version (or the Audacity version) would make a difference.

How are you doing that? Is it Internet radio or do you have a radio connected to your soundcard? Is it a mono broadcast?

...You might have to record in stereo and convert to mono after recording.

Yes, what I mean is setting the "Project rate" to 22 kHz to down-sample a 44 kHz audio.

What do you mean by "caching"?

By caching, I mean TWO things. 1) is Audacity holding-up the App until the export is complete, and 2) I have RAM caching software called Diskeeper. I'm finding the export is taking too long and it's choppy. Apparently Audacity doesn't play well with RAM cache software. Not an expert here. Thx

Yes Thx, I tried those settings and it still records in stereo.

It started around the time I upgraded to 2.4.2 — and assuming it's because of incompatibly with Win7. Haven't been using Audacity every day like I used to, so probably forgot a procedure. Have been recording streaming talk shows (mono) and ripping sound from videos—these videos are usually 44 kHz but a talk show doesn't require 44 kHz rate. So I set the Project rate to 22 Khz, Export, and when playing back the audio, its tempo (or pitch) his high like a mouse and the overall LENGTH of the waveform is smaller in terms of Mins.

I'd very much like to KEEP the preferences the same. Is the new Preferences INI file different from the old? Thx

You can't convert streaming audio between stereo & mono while recording. You are "capturing" the digital audio stream. And with WASAPI loopback I'm pretty sure you can't resample on-the-fly, but I haven't tried it.

But, you can change the Project Rate and/or convert to mono after recording.
