      I plan to convert 30-45 minute individual voice only recordings in mono sound from Philips cassette tapes to flash drives. I have a few questions. First, what capacity flash drives will I need for a 30 minute recording separate from a flash drive for a 45 minute recording? I do not wish to put more than one session per flash drive. Second, once I have converted the recordings to flash drives, does this mean I can then transfer the content of the flash drives to CD-R discs? I have a Windows 10 computer. Does the Windows operating system have a built-in conversion procedure to do this? If not, what is the best or easiest to use commercially available software program I can buy to accomplish this? Finally, what (if anything) is similar to a PDF file as an email attachment that can store an audio session? Will any recipient be able to click on the attachment to play the audio file without having to own the same software program? Thanks.

      Hello Kirk,

      The audio file size has been calculated below, using the free tool here.

      The largest file size is roughly 250 Megabytes, you may have trouble finding small enough flash drives for each file. Still not a bad idea to keep a backup copy on flash media.

      You can click here to see how to burn Audio CD’s and Data CD’s for archiving your media.

      Minutes: 45
      Settings – Uncompressed (WAV, AIFF etc.)

        This may sound like a dumb question, but how do I know if the source audio file is compressed or not? (I will be transferring mono sound from Philips cassette tapes to WAV file via Flash Drives. I furthermore do not know what bit rate the original sound files are in. (or does that even matter?) I have no control in using the cassette recorder to adjust anything. It just does the job as do countless ordinary cassette recorders since inception. Thanks, John

      Hello Kirk,

      The cassette tapes are analog, so the bitrate does not apply.

      Now speaking of .wav and .mp3 format, .wav is uncompressed .mp3 is compressed audio. You do not have to be concerned over what format your record with.mp3 is enough.

      You can take a look here if you need a way of recording from your existing cassette player, then pair that with a free version of Audacity to record what you are playing on your workstation. Audacity works with PC or Mac. You can click here for a YouTube video showing you how to use audacity and the RCA to USB adapter in the previous link.
