My 4-Track Yamaha does 40 Hz to 14 KHz, a good HiFi cassette player should be way better. Regarding frequency response the cassette player's maintenance is much important, to allow proper recording. If the tape heads and capstans were demagnetize on a regular basis, the recording quality of a good cassette player isn't that bad, so high quality digitisation might make an audible difference. However, I don't know if a cheap audio interface is good enough, but the interface might be just a part of the digital chain, sample frequency, dithering, good software are important, too. I tested mastering my 4-Track recordings with a Yamaha DAT recorder at 32 KHz, 12 bit (2 Hz to 14.5 KHz), which was good enough for most recordings, but sometimes it did cause artefacts. 48 KHz, 16 bit (2 Hz to 22 KHz) was always good. Comparing my RME HDSPe AIO Linux audio recordings of high quality audio signals (I never recorded audio from a cassette player with Linux) with the Sony DAT recorder, the audio quality of the DAT recorder is way better, while the monitoring of the RME HDSPe AIO is without audio flaws, issues are present when playing with Linux recorded audio signals. However, we don't need to discuss any claim, neither Jeremy's 12kHz, nor my Linux recording issue claim, instead just order an audio interface, make a few test recordings and if you shouldn't be satisfied, return the audio interface to the dealer. Important is only what you are able to hear. Btw. the audio quality of my Behringer ADA8000, my Focusrite Scarlett 18i20 (2nd gen), my TerraTec EWX 24/96 and a Presonus 1818VSL I returned to the dealer is less good, than what my end of the 80s cheap Pioneer HiFi amp is able to perform, just the audio quality of the RME HDSPe AIO beats the aged HiFi amp's audio quality. I wonder, if the analog domain of a Behringer UCA202 could keep up with the output of a good HiFi cassette player. The cassette player output does bias the sound, as well as the analog input of a cheap audio interface. -- pacman -Q linux{,-rt{-securityink,-cornflower,,-pussytoes}}|cut -d\ -f2 4.20.2.arch1-1 4.19.15_rt12-0 4.19.13_rt10-0 4.19.10_rt8-0 4.18.16_rt9-1 _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx https://lists.linuxaudio.org/listinfo/linux-audio-user
