Amiga A1200 High Resolution Audio Capture

I'm working on a customer's M-Audio M-Track MkII and couldn't resist the opportunity to test it by using it to capture the audio output from the Amiga A1200.  This is the same Amiga 1200 with the Rev 1A board which I've blogged about previously.

The M-Track MkII is a 2 channel analogue to digital converter and I have it connected to a Linux PC running Fedora 26 which immediately recognised the device and it showed up as as both a stereo input and output device in Pulseaudio.  I used Audacity to record and edit the audio at 48kHz stereo, exporting as 24 bit FLAC.

The M-Audio M-Track is a pretty awesome bit of kit and worked well under Linux.  I was even able to play audio to the device and mix between Direct (analogue) Input and USB using the front panel mixer control.  Very nice indeed.

The Amiga audio captured directly from the rear panel L+R phono sockets also sounds amazing.  Unfortunately I don't have another A1200 to compare with so I don't know how this Rev 1A computer compares with later hardware revisions.

You can download a selection of audio files in FLAC format here which are obviously quite big being lossless:

Google Drive - Amiga A1200 Audio Files

The files available are:
  • A1200_mod.chippermodphosis_maudio.flac
  • A1200_mod.fresh_house_maudio.flac
  • A1200_mod.human_invasion_maudio.flac
  • A1200_mod.milk_punch_maudio.flac
These are just a few of my current favourites which I've been using for testing and repair of this particular A1200.  Only Amiga makes it possible!
