I have just bought a Behringer UCA202 to record my mixes to my laptop. Plugged it all in and seemed to work ok, but when I exported and had a listen back something is not right. There seems to be a mild buzz, echo and distinct lack of bass even though all my levels seem to be ok. Connections are direct from Pioneer DJM400 mixer into the UCA202 and then into laptop.
Below is the sample mix I used to test (wetransfer download)
So you have a significant amount of 50Hz hum. This is typically caused by bad or conflicting grounds or defective or sub-par cables. You can experiment with the Nyquist Hum Remover: Missing features - Audacity Support and/or High-Pass Filters and Noise Reduction, but I don’t think you are going to be able to remove all of it - so find the source of the hum and remove it.
The only issue I am facing now is that either Audacity or the Behringer randomly seemed to speed up and slow down a melody on one of the tracks! It is from the time stamp 5:50 and as it breaks you can then hear the background melody altering in speed.
Any idea what would cause this?
I think I also need to adjust my levels, any suggestions on that too would be great.
Thanks
