Hi. Thanks for the responses.
I’m using iPhone XR.
Yes I’ve previously recorded from the same master out into my Mac using audacity and never had problems. It’s just a faff then having to edit/split tracks/import etc. I wanted the Evermix box to provide convenience and better sound recording quality. I can also record I to the P4 hard drive without issues.
Did another recording this morning - just put the P4 into continuous mode for half an hour. This time with the limiter setting off and keeping the level below 0. The recorded waveform had plenty of headroom and yet 10 mins into the recording the full on distortion bit crush sound kicked in for the remainder of the recording.
I’ve even tried replacing the RCA cables with more heavy duty insulated cables in case there was some kind of interference, but made no difference. Another unsuccessful recording.
An interesting point made by DJ Sontag - I’m currently recording at 320 AAC to save space. It does have a WAV ability so will try that and see what happens. It does feel like the box/software is struggling to keep up with a long recording. Recording individual 5 or 10 min tracks seems ok.
Otherwise I think I’ll have to go back to the traditional lap top recording or internal hard drive method.
Think I’ll get in touch with Evermix and try and get an exchange and see if it happens on another unit. This unit is designed to do live recordings in clubs and upload to soundcloud etc, but if it can’t record more than 10mins without failing it’s pretty useless.
