Hi Folks

As promised at Dayton here are the new AMBE Tools programs. One of them, DVToolReader was included elsewhere, but has now been upgraded considerably.

This suite consists of six programs, two are GUI based, DVToolReader and DVToolWriter and the rest are command line. All can work with either the DV-Dongle or the new DV3000 from NW Digital Radio. At their root these programs are designed to convert audio data to and from WAV files to either .dvtool files for the VoiceTransmit program, or for the announcements within the repeater, or to .ambe files for creating your own "Linked to" announcement, or even time ones. In all cases the WAV files should be mono and sampled at 48000 samples/sec.

The settings for wav2ambe and wav2dvtool are taken from DVToolWriter, and for ambe2wab and dvtool2wav from DVToolReader.

In addition DVToolWriter can record a microphone straight to these file formats.

Like the newly released Dummy Repeater, these programs can use the DV3000 which is hosted on a Raspberry Pi, and the same comments about the dv3000d running on the RPi apply.

For some reason, I can't upload my files to Berlios so the only source for the software is currently via this group.
