KCT Posted September 21, 2006 Report Share Posted September 21, 2006 Hi,I was just wondering, using a MDS-JE510, can I record square waves and replay them undistorted ?CheersKay Quote Link to comment Share on other sites More sharing options...
A440 Posted September 22, 2006 Report Share Posted September 22, 2006 As you know, square waves are tough. Since that deck is SP at best, it's going to compress the input, so it depends on what you mean by "undistorted." Quote Link to comment Share on other sites More sharing options...
raintheory Posted September 22, 2006 Report Share Posted September 22, 2006 BTW, SP = ~292kbps if I recall correctly. Quote Link to comment Share on other sites More sharing options...
BobS Posted September 23, 2006 Report Share Posted September 23, 2006 You will get distortion. Square waves look like a whole lot of frequencies added together. Since even 292 kps throws away 80% of the data, it will be distorted Quote Link to comment Share on other sites More sharing options...

ZosoIV Posted September 24, 2006 Report Share Posted September 24, 2006 Square waves are difficult to correctly reproduce with 16-bit, 44.1kHz PCM, let alone compressed ATRAC audio. The question is, will you be able to hear the distortion? Only your ears can tell you - don't rely on spectrograms and scopes to determine how something sounds; pictures can be misleading when it comes to audio.

KCT Posted December 3, 2006 Author Report Share Posted December 3, 2006 Thanks for the replies.I am intending to use the deck to record a sort of slow data stream rather than music. I am just curious if the data stream can be reproduced accurately without bit errors. I am not so interested in the actual audible performance with square waves at this point, yet this is very important for true audio reproduction.CheersKay Quote Link to comment Share on other sites More sharing options...

This sounds interesting. I have been wondering as of late if I could use my minidisc with my Commodore 64 emulator as a tape drive. Quote Link to comment Share on other sites More sharing options...
KCT Posted December 3, 2006 Author Report Share Posted December 3, 2006 Hi milomind,well, I have something very similar in mind, the data stream I try to record and analyze is the PCM of a RC remote control system used for RC airplanes and such. Provided the distortion of the square wave signal is not to bad it shouldeasily be possible to store this kind of information so as old C64 and Atari programs. If I have some spare time and get to it, I post some results.CheersKay Quote Link to comment Share on other sites More sharing options...
BobS Posted December 4, 2006 Report Share Posted December 4, 2006 Recordings of this type should be fine. Distortion is common on all media, including analog tape. The square waves are distorted going down the cables, due to capacitance effects of a cable. Software that reads the signal can deal with the distortion unless it is excessive. If it was something designed for cassette then a frequence response only to 8-10 Khz was orginally a design parameter. You should be fine using a higher bit rate. Give it a try. The worse that can happen is it won't read it correctly and you will have your answer. Quote Link to comment Share on other sites More sharing options...
