Dalek speaking!

In have recently installed Mountain Lion OSX on my iMac. I am running Audacity 2.03. When I did my usual weekly recording today from the radio, the result sounded deep and echoing like a Dalek speaking. Completely unlistenable!
I’d appreciate some help here.

What type of radio - web radio recorded using Soundflower, or a physical radio using the Mac line input?

What sample rate did you record it at? Did you change your device settings in Apple Audio MIDI Setup?

Can you export about five seconds of the recording as a WAV and attach it? Please see here for how to attach files: https://forum.audacityteam.org/t/how-to-attach-files-to-forum-posts/24026/1 .


Hello Gale. I’m using Audacity 2.03 with Mac OSX 10.8.4

Audacity is recording ac Community Radio Station at 44100 using Mac inline

File is attached.

I thought I might have solved it, when I discovered that the Sound setting on my newly installed ‘Mountain Lion’ was on ‘Internal Microphone’, but it’s now on ‘Line In’, which is where it’s supposed to be. I made no changes to the settings except that the Audacity input settings seem to have to be lower to get any sensible recording at all.


The Mic-In thing was going to be my first guess. Macs do not have a natural, built-in way to record internal sound like many (but not all) Windows machines. We have found that using the SoundFlower add-on software is a good way around this.



Thanks Koz.
