Our 1/4 inch 4 track reel to reel tape transfer service records your ¼" (quarter inch) 4 track reel to individual digital .wav or .aiff files. This audio tape to digital conversion lets you remix the tracks in a modern Mac or PC digital audio workstation like Pro Tools, Cubase, Nuendo, Logic Pro X, GarageBand, or Reaper.
If you have a ¼ inch 4 track tape that you would like to remix digitally, contact us now for a quote and directions on sending us your tapes for conversion.

The quarter inch 4 track format was first developed for home quadraphonic recording in the 1970s. Musicians quickly discovered they could record 4 individual audio tracks for different instruments. Realizing this, TEAC created the A-3340 for recording studios, supporting larger 10.5" reels for longer recording time. Despite being created many decades ago, 4 track machines are still used to this day.
Older 1/4" tapes, mostly AMPEX/Quantegy and fewer formulas of 3M/SCOTCH, are unfortunately prone to "sticky shed" syndrome, due to the breakdown of the binder (glue) holding the oxide particles on the tape. Tape baking may be required for the transfer of older, unstable tapes. We have perfected the process of treating and rescuing these tapes (even those suffering from severe sticky shed). Let our team of seasoned engineers handle the delicate process of saving your recordings, giving them an infinite lifespan in the digital domain.
If a track sheet came with the reel, send it along — it tells us the track count, tape speed and whether noise reduction was used before we load the tape.
