a few months back, designboom covered designer amanda ghassaei’s 3D printed records – functional prototypes that would play on regular turntables. just like any vinyl record, she attempts to reproduce accurate soundbytes by converting digital audio files onto laser-cut records with a precision of 1200dpi. unlike hi-fi audio, the acoustics are rendered in a resolution of 4-5 bits (typical mp3 audio is 16 bit) and a sampling rate up to about 4.5kHz (mp3 is 44.1kHz).
