Okay, I'v managed to find Perkins branded Digital Cartridges on Amazon, but there doesn't seem to be any listings for the cables. Does anyone know if the cartridges include the cables? Either way, I'm tempted to pick up a 16GB cartridge as a stop gap for playing the encrypted files if I can't figure out how to play them on my Blaze ET or Linux PC, though considering how anemic 16GB is for storage this day and age, I find myself wondering if my digital cartridge player can play audiobooks stored on an SD card in a dongle-style reader connected to the USB port on the side of the player. *Tries it with the 256GB card from my Blaze ET.* Okay, its been beeping for a few minutes and the pause, fast forward, and rewind buttons just play a please wait message with no explanation. I can only assume its trying to scan the SD card for compatible files. Given a suggestion to use a standard tape deck to rip two of a cassette's four tracks at a time and do post processing to account for tapes having non-standard formats, I've been searching for a suitable one on Amazon, and while there are several rather affordable models designed specifically for converting cassettes to digital files, it isn't always clear which models are stand-alone, which rely on a PC and specific drivers, and which should work with any recording device with a line-in/microphone jack, and many sound like they're hardcoded to output mp3, which I deem completely unacceptable in this age of terabyte harddrives and 256GB memory cards, and even cutting record time by more than half isn't worth lossy compression when I already have a recording device with line-in and wav support, and there's no mention of sample rate or bit depth on any of the product pages I've checked. If anyone has any suggestions for cutting through the cruft, it would be greatly appreciated. I've only ever used sox for concatenating flac files, but I understand its one of the most versatile command line tools for manipulating streamed audio. Can anyone provide instructions on how to do the following tasks in sox or via another command line tool? -Reversing an audio stream in a way equivalent to playing an audio cassette backwards. -Altering the sample rate for playback without altering the samples themselves. Also, am I correct that, if your analog source is playing at double speed, you'd want to record at twice the target sample rate before slowing the recording down? -Splitting multi-channel files into single channels files or merging single-channel files into multi-channel files. -Trimming silence to a given length at the biginning/end of a stream or splitting a stream into multiple files in the middle of internal silence exceeding a certain length. -Anything else that might be useful for the task at hand. Oh, and my digital cartridge player eventually finished whatever it was doing, but still offered no explanation, not even a "no content found" message. The contents of my SD card seems unaffected putting it back in my Blaze ET. Sincerely, Jeffery Wright President Emeritus, Nu Nu Chapter, Phi Theta Kappa.
