Floppycasts – 1.44MB Podcasts

Here is a short list of some of the codecs I tried, and the smallest size I was able to get out of them for 30 minutes of speech that was still inteligable:

Now I was performing these transcodes from a wav file that I had processed in audacity as I will describe below. Then I encoding the resulting wav file with opus at between 6 and 10 average Kbps, variable bitrate, tuned for speech. I was unable to get the OPUS file to play back in any other programs on either OS, and I was never able to get the OPUS file to play back on anything in my collection slower than a Pentium MMX (although it has been suggested that a high end Pentium, or possibly even a very fast 486 should be able to handle it, I don’t currently have rigs available for testing.)
