cork cantilever damper

Recording system, v. 6 – switching to a more wide-band and clear SE-piezocrystal caused problems with the tone balance, especially on the HF, where the resonance of the “crystal – damper – cantilever” came out of the shadow. Depending on the type of adapter and cantilever, it could be reduced as much as 7-8 kHz, which, of course, was unacceptable. There were two solutions — to use a flexible factory adapter that suppresses the resonance by 90%, or to somehow reduce the weight of the system.

Homemade SE piezo crystal

The recording equpment, v. 5 – a factory crystal of the late 1950s made of some compressed powder (barium titanate?) was used in recording system until recently. A common vintage piezo crystal consists of two plates, folded in the same planes together and wrapped in paper to give them strength. Factory crystal elements are always doubled and connected so that the external interference at the output is subtracted, and the amplitude of the useful signal increases. Technically, dual piezo pickups have only advantages, but subjectively they sound less clear than single-ended ones, just as a push-pull amplifier stage (PP), with other things being equal, sounds less clear than a single-ended (SE) one.

Macromedia mp3 encoder for Mac Classic

So far, AIFF files have been compressed on Mac G3 using the built-in encoder of the Audion player. From the three versions (standard, Lame, and Pro), the standard encoding was initially chosen, although the Lame allowed you to get files of similar quality with a lower bitrate. The clarity of Lame was also somewhat higher, but it worked unstable and had to be abandoned.
