wav2pzx
Convert ZX Spectrum tape recordings to the .PZX format
V3.0 Speed and Asymmetric Pulses
- The updated PZX encoder is much faster, especially for long tapes
- It can also now decode many loaders with asymmetric pulses like the Software Projects loader used in BCs Quest for Tires.
- The source WAV should be recorded with the maximum volume possible without clipping.

Overview
The Sinclair ZX Spectrum and related computers primarily stored their software on audio cassette tapes. While most emulators for these machines support the TAP and TZX file formats to efficiently store that software, they are either limited in what software is supported (TAP) or overly complex to support (TZX).
The PZX format is a more recent attempt to produce a flexible format that can support all software produced for the ZX Spectrum and related machines but is relatively simple to encode and support.
This program translates a recording of a ZX Spectrum tape in WAV format (preferably a mono 8-bit file with maximum volume without clipping the samples) into a PZX file, recognising the standard Spectrum files saved by the ROM routines, many custom loaders and preserving any data it doesn't directly support.
It currently expects to be run from the command line and has the following arguments:
$ java -jar wav2pzx-3.0.jar <infile.wav> <outfile.pzx>
