I used to use audacity 2.1.1 on my windows PC to record dj sets from my Pioneer XDJ-R1 with no issues. I now have a macbook using Audaicity 2.1.1 for mac (DMG) and the recording volume on the waveform is really small and I cannot figure out how to get it to just be the same as when I was using it on windows.
By stereo input do you mean the headphone jack? It does but I thought that was a mono input? I tried using an RCA to 3.5mm jack from the booth out of the mixer to the mac headphone jack but It didn’t recognise any signal coming in … and then I added a TRS to TRRS adaptor to reverse the flow, which worked but the quality is not there.
Is there a fix for this without having to buy an external sound card?
Exactly so, if you buy a Mac that does not give you high quality (line level) audio input.
Perhaps you could take analogue outputs of the mixer and feed them to a USB device that has an input gain control like ART USB Dual Pre. But first you should check that your levels out of the mixer really can’t go any higher.
