Too Many IssuesAlthough some of the other reviews weren't the best, I've had no problems converting old cassettes to audio file. Plug in a USB flash drive, hit play to start the cassette, then press the "record" button. Automatically stops at the end of the tape.As others have mentioned, this saves to a WAV file. My audio editing software (Goldwave) shows the following when opening the wav file:"Wave Microsoft ADPCM 32.000khz 4 Bit Stereo 259kbps"Thus the WAV file produced on this tape player is probably similar to mp3 quality. A CD quality wav file would be overkill and produce needlessly large files.Oddly enough, if I open this file with VLC, it says "16 bit stereo 259kbps sample rate 32.000khz". Don't know why I'm getting two different bit rates.For reference, CD quality WAV files are:16 bit 1,411 kbps sample rate 32.000khzAlso, whenever I open the wav file in Goldware (my audio editing software), I'm met with the following message:"Internal date size is incorrect, the file may be corrupt, continue anyway?"Fortunately, the file does open anyway, and it's easy to convert to mp3. I've never seen this error message before, and I've been using Goldwave for about twenty years. So, there's something slightly 'off' about this wav file, but works anyway.Update: The cassette motor is a bit weak. Sometimes the tape won't start when I press play. I then have to take the cassette out, put a pencil in the cassette hub, turn the hub a few times, put the tape back in, then it works.Update 2: I've downgraded the review from four to one star. After only a few hours of use, the player has become un-useable. When I play a cassette, the sound will sometimes be extremely muffled. If I load the tape again, it sounds OK. It's as though the heads do not always line up properly with the tape correctly (only sometimes).0
