From Colin Leroy-Mira:
Wozamp is a simple network music player for the Apple II. It can:
- Browse a network share (FTP only) and play sound media files.
- Play an entire directory
- Fast-forward and rewind
- Display cover art embedded in media files
- Display a VU meter
- Stream from online webradios
Requirements:
Wozamp should run on any 64k Apple II with a serial card. In addition to that, it requires a surl-server proxy to handle the transcoding and resampling.

Installing the surl-server proxy:
See the dedicated surl-server page.
Transferring the floppy to your Apple II:
Download the latest floppy image from the Github Releases page. Use the image corresponding to your Apple II:
Apple II model | Floppy image |
][+, IIe, 6502 CPU with 64kB of RAM | wozamp-oldii.dsk |
IIgs | wozamp-iigs.dsk |
//c, //c+, IIe enhanced or platinum, 65c02 CPU with 64 kB of RAM | wozamp.dsk |
Transfer it to your Apple II using ADTPro.
The Audiophile metrics
Wozamp achieves a very tolerable sound quality thanks to the use of a 11.52kHz sampling rate and a state of the art 5-bit DAC. You can enhance the experience further by replacing your serial cable with a gold-plated serial cable (*actual results may vary).
Thanks
Many thanks to Oliver Schmidt for his KansasFest presentation of A2Stream, which made the theory of PWM clear to me. I want to make clear that I did not invent any revolutionary concept here: pulse-width modulation sound has been made long ago, at least since 2005 by Michael J. Mahon, by Oliver with A2Stream, by Kris Kennaway with II-Vision.
I think my only innovation is to do it over serial, making it possible to stream music from the network with an Apple //c, the one computer in the series with no expansion slot and no way to add an Uthernet card. But I’m not even sure. I just wanted to do it.
Thanks also to Bits&Terminal Jeff for the very cool name idea!
