Chris-Another tool is to combine the tracks while listening.Making it mono. The azimuth setting is most easily fine-tuned that way--Mickey -----Original Message----- From: Tim Gillett Sent: Wednesday, October 21, 2020 2:47 PM To: [log in to unmask] Subject: Re: [ARSCLIST] Delayed Channels on Cassette Tapes Hi Chris, I'm not sure if you know that cassettes are notorious for azimuth misalignment on playback. Experts in tape digitization align the tape replay head to the recorded patterns on each tape being played. It involves carefully adjusting the azimuth screw on the machine's playback head while listening. We aim to extract the brightest, clearest sound off the tape. After this has been done, an Azimuth Corrector tool might be also used to fine tune the small remaining misalignments, especially dynamically changing misalignments which occur too quickly to be corrected by adjusting the head's azimuth screw. An Azimuth Corrector is generally not very good on a true stereo recording as it can struggle to distinguish between intended and unintended inter channel delays.

A batch of them are stereo, however they have exaggerated separation of the channels (perhaps they need normalisation?), and one channel is a microsecond behind the other. We don't actually need stereo, amd have tried to merge the channels into mono. But this sounds dreadful - the speech part sounds OK, but the music is very 'echo-ie). Another batch have delays from one channel to the other measuring in seconds. How can we time-shift one channel to match the other one?
