Hello, been quiet lately because I’ve been working on learning the proper recording and mixing side of things, which has led me to a strange discovery. I’ve started recently using the SoundOut effect and piping channels into Ardour to flesh out tracks I was making before I started using SPi for MIDI sequencing. I’ve noticed some really weird anomalies from sounds that I record this way. Basses will unexpectedly warble and the bottom will disappear so that I have to boost and compress. I can see my <20hz rattling around. While I can use an HPF to fix that for a lot of sounds, it’s not practical on the bass. Also when I render out samples that are heavily chopped, (ie my breakcore tune) I can see what looks like a DC bias at the end of some of the slices, even if I chop off what I can see (yeah, I did that with every hat on a 7 minute breakcore tune ) I still can hear ticking when the ample is in isolation. The final symptom of this issue comes up in Audacity. If I normalize with “adjust for DC bias” on it will actually offset the DC by the relative amount of level adjustment. One track I was working with last night is now entirely unipolar, which in this case is kind of cool because it’s some freaky bitcrusher mixing, but even if I add silence manually and play it back, the output reads 100%.
The only thing I can think of is maybe Mono is virtual in SPi and stereo subs are phase cancelling? Is there something I can do to ensure a pure Mono? SoundOut is still fairly new to me so I might be missing something.
