Letter tape, 1974, sample.

Forgive the clicks - the tape is almost 43 years old and has been stored in various places in that time. Transferred from 1/4" open tape, originally recorded at 3 3/4 ips but played back at 7 1/2 ips and slowed digitally using Audacity DAW software. Source played from TEAC A-3340 reel to reel, recorded on Apple iMac via Focusrite Scarlett Solo 2nd Gen audio interface.
