Why is this hold music so low quality?
most likely because they’re using the g.711 standard of narrowband audio quality. a 64 kbit/s bitrate paired with the 8khz sampling frequency doesn’t allow for much in the way of audio data and is generally pretty limited to a small section of the audio spectrum (in this case, 300–3400 Hz).
while its okay for something simple like the human voice, it can only handle a limited amount of audio data before it loses a bunch of detail and becomes a rather garbled mess.
