Collected by grandpa. Here are mostly real hits (from 30s to 50s)
These are in WAV (11kHz, 8-bit, uncompressed): this format works much better than MP3 with such exotic sound source as grampophone disk (very noisy, with wery narrow band for useful signal, about few kHz).
Recorded using ancient tube radio-gramophone, which has excellent noise reduction filter, designed specially for gramophone disks (but don't ask me, how many sound cards died on their duty - for in any tube amplifier average voltage is around 200 volts)
Note: there are .TXT files included into each archive, but all details are in Russian.
