Er, minor correction, the effect I was talking about on the tune (where the echo is more part of the sound than perceived as a repeat) is the bass and the textural chordal change thing most easily heard in the sparse section starting at 1:37; my buddy added all the mallet things with echo

Being a long-time fan of delays (and author of Echo farm PT plug-in and DL4 delay modeler stompbox), starting with tape delay (first a Univox tape delay, graduated to Roland Space Echo (the space echo emulation in Echo Farm is based on my aged RE-101)…when the digital first came in, it was neat

Whenever vintage delays come to my mind, I hear the sound of the bucket brigade delay lines that were made from a chain of capacitors and switches. In the early 80s there were many electronic magazine articles and kits to build them. The SAD chips had a maximum delay time of about 200ms. Were they

The first delay of which I was aware was in the piece Echo III played on the viola by Tim Souster in Cambridge in the early 1970s. Not an echo or reverb but a cannon. Delay was via two reel-to-reel tape machines, with a carefully measured distance between them. I cannot remember if it was the

Hi all, No theoretical dumbfounding or deep searching incantations from me this Monday, but just something I've through about and that somehow has since long been a part of music and analog and digital productions. I recall when I was doing some computer audio experiments say in the early

Related: Using separate reverbs on each instrument in a DAW recording gives a richer mix that just a single reverb on the master channel. Back in the analog days, you'd use the multitrack tape and mixer to do multiple passes through the best reverb in the studio. In the early DAW days, you'd

Most of the old delays were BBD, but the king of discrete-time analog was the Marshall Time Modulator, which used CCDs. Between the dbx companding for increased s/n and the wide clock-sweeping range, it had awesome flanging (-80dB notches claimed)—great double/triple tracking too. On Jul 20,

To add to Robert’s comment on discrete-time analog… The only thing special about digital sampling is that it’s stable (those digital numbers can be pretty durable—the analog samples don’t hold up so well) and convenient for computation. But the digital audio samples are just a representation
