After trying the online tool referenced, I found two major (show-stopper) issues :
limited use (you need to register/pay for unlimited conversions/batch conversion)
unusable AAC files (bad bitrate).
After looking a little, I found an OPENSOURCE and FREE solution working at least on Windows and Linux (I don’t have a Mac computer) : Fre:ac (previously BonkEnc).
In the filter options, you need to activate two filters : the channel (set to mono)- and the samplerate (set to 24000).
In the encoder, you need to put FDK-AAC and configure it for 64kbps and AAC (AAC is on the second tab).
Il allows batch-encoding (but better go to optios->encoder and set file name to something without a directory name for example - ).
When writing the usage guide, we were looking for something users could easily use without installing any third-party software, so the online tool we referenced was a natural choice. It seems, however, since then the tool has changed, and we’ll update the guide with a better alternative ASAP.
Thank you for letting us know about the changes and suggesting an alternative. We’ll look into Fre:ac and some other alternatives and put them into the Jay-D usage guide in the near future
