Hi all,

I have spent days on something that has, in my experience with other software, been straightforward. Probably something I'm missing as Bitwig has a different way of doing quite a few things! I'm using Bitwig 2.3.5.

Creating some percussion samples. Pretty simple stuff. (Pic tells a thousand words and tried to post screenshot but need 60 karma points). I have recorded percussion using two mics on to two separate audio tracks. Long takes of single hits and experimental sounds on one percussion instrument to slice into smaller sections to use elsewhere.

After that process, I now have about a dozen instruments recorded, six of them using the two mics. I will make clear that these are not stereo tracks left/right and not wanting them to end up that way together on a single track. They are mono tracks, centered. The mics (for the curious, a Behringer C-2 condenser bottom and a Rode NT2 up top) were placed top and bottom of the instrument so, obviously enough, they were never intended to be L/R config.

I realise now that I would have made life easier for myself by recording the two mics to one stereo track in the first place, but the reality is that I didn't and here I am. Would rather avoid repeating the process, if possible.

I have created an empty audio track and routed the two percussion mic tracks with recorded percussion to that track. All good.

Play the samples, meter on the receiving audio track bobs up and down, receiving signal. But only when the record button is not enabled. If I arm the audio track and try to record the two mono percussion tracks (in this case bongo) onto the audio track, the meter on the audio track stops bobbing and it creates an empty audio track. Nothing on it.

I tried the export route a few times - Export> Select tracks to export and other details - which looks ideal for what I'm trying to do, but that produced no files in the folder I'd designated.

So would anyone have any idea what's happening? Am I missing something? Starting to think I should have recorded the percussion in Audacity to start with and chopped up/exported from there, then simply used as samples in Bitwig, rather than trying to do all that in Bitwig. Was I trying to kill a mosquito with an elephant gun by doing this in Bitwig? Perhaps.

All input (no pun) appreciated, and in the meantime, I'll keep playing around.

(PS: I did try selecting both tracks and bouncing them to one track. That left me with a hybrid track, not an audio track, which is what I want (although both tracks did end up on one track, so step in the right direction). It seems Bitwig can change an audio track to a hybrid one, but I can't see any way of converting a hybrid track to an audio track.

I also tried putting the two original raw tracks in a group, routing them to the group master and routing the group master to the audio track to record. Same thing; it works and the meter on the audio track bobs as if ready to receive, but when I arm the track to record, it records an empty track and not bobbing meter.)

Hi @Bucky,

Ok first of all, if you are recording anything with 2 mics (eg a drum, one above one below), I don't advise that you record the two mic signals to a single stereo track (mic 1 left - mic 2 right). You first, want to keep them separate, so that you can adjust the phase relationship between the 2 signals to minimise the effects of phase cancellation. (Exceptions to this would be recording instruments where stereo information is important i.e. pianos, xylophones, where you are intentionally mapping the 'keys' across the stereo field).

If, as you are trying to do, put 1 signal on the left and 1 signal on the right, without fixing the phases first. You will create a wider sounding signal but chances are, it will not be mono-compatible if your music is played on a mono system, there is a good chance some, if not most of the sound will 'disappear'.

What you will need to do first is this:

Insert the two mic recordings onto two separate audio tracks and then group the tracks. Next you want to line up the phases of each recording.

There are several techniques to achieve this.

Sometimes all that is necessary, is to insert a Tool onto one track and flip the phase (This is especially applicable to mics above and below a drum skin, where the phase polarity is most likely to be opposing). You can add a Time Shift device to one of the channels and offset the timing until it sounds good. Or, the more accurate way is to zoom in on both waveforms and line up the peaks of the waves so they match. Then you can start to think about combining the two signals.

I don't have any similar material to test this but now you should be able to select the clip region in the grouped track lane and bounce it out. I suggest you bounce to a new track at 32-bit for top quality. Before you bounce, I would also suggest you make sure the balance between the two tracks is as you want it, i.e level, eq etc.

Once you have matched the phases and bounced, only then should you be thinking about chopping it up into samples etc.

One last tip, in my opinion, it's best to try and work with mono tracks as much as possible and then place them in the stereo field as you see fit. Having too many wide stereo tracks in a mix causes all kind of issues.

Please let me know if this is helpful.

Upvotes are always appreciated.
