So i use my android phone to record my digitone2 on the go.
Lid like to use the app J4T to record multiple tracks (one after another). But when playibg back a track its l sounds like its super samplerate reduced / distorted.
The recorded file itself is fine, its just playing back sounds through digi from the phone thats fucked up.
I set the samplerate to 48k in the app.
Any ideas?
Are you using the Digitone 2 as a class compliant audio interface for your phone or are you listening to the tracks directly through your phone?
I’m assuming the former…
Using it as interface, headphones in the digi
Ok so you’re using the Digitone 2 as interface previewing the Digitone 2 audio being input to the Android app while the digitone 2 audio simultaneously plays through the headphone out?
If I’m understanding correctly, the audio has been recorded to the android. The recorded file is fine. The phone is playing back the audio using the digitone 2 as the audio interface and headphones are plugging into the DN2. The audio playing back, when monitored through dn2, is somewhat distorted or sounds like the sample rate is being reduced, but the audio in the file itself is fine. Is this correct?
Exactly!
I’m only theorizing but I would suspect you have not compensated for the USB audio volume by using the USB to main feature in the device’s audio routing settings menu
I would suspect you cranked the volume on the android or on the digitone itself in order to get a proper monitoring level and something akin to a gain staging issue is occurring.
What I would do is turn the android volume to about midway and turn the digitone volume to a normal listening level for one of your tracks, then adjust the USB to main parameter. Go back and forth between the android volume and the USB to main, slowly bringing the android volume up to meet the USB to main compensation you’ve set. Try to do this while leaving your main DNII analog volume pot at the level which is also good for the internal tracks.
The USB to main parameter can add up to +18db so I think that you’ve inadvertently reduced the audio quality by saturating the signal via overcompensating with the main volume pot.
It’s a very easy mistake to make so I wouldn’t worry about it too much. Also, if you’ve already done what I’m talking about you can disregard, but this was my first thought when reading your post.
Let me know how that works for you.
Also, it’s listed on page 77-78 in the user guide if that will help at all.
Yeah, this sort of thing is ambiguous enough that you just have to try a series of things to correlate to what’s out of normal operation.
@prydal Have you used the DT2 as an interface for any other audio apps successfully?
