1.4.1
New features:
Several new sync types for existing formats now recognized:
Decodes voice from NXDN 4800 (6.25kHz) signals
Decodes voice from NXDN 9600 (12.5kHz) repeater output
Decodes voice from DMR/MotoTRBO simplex/repeater input
Decodes voice from X2-TDMA simplex/repeater input
Fixed bugs:
renamed "input:" to "inlvl:" to reduce confusion. This value
indicates the audio input level, NOT the "decode success
rate". Voice decode errors are indicated by the errorbars "=".
1.4
New features:
Decodes voice from NXDN 9600 (12.5 kHz) simplex/repeater input
NXDN96 frames enabled by default
Improved resistance to NXDN96 sync false positives
Fixed bugs:
.wav file header updated after playing .imb/.amb data files
.imb/.amb files now have correct tgid in filename
1.3.1 New features:
Support for ProVoice EA sync
CTRL-C is now caught so .wav files can be properly closed
DSD now shows mbelib version as well as it's own version
-R resume option now triggers on any TSDU so control channels can be left
in conventional scanlists.
Auto output gain now has 0.5 second hold time for faster error burst recovery
(was 1.5 seconds)
Audio output upsampling function simplified and improved
Fixed bugs:
DSD_Author.pgp now has correct public key (was copy of mbelib_Author key)
TGID and SRC are now cleared after TDULC or TDU.
Voice error counter is now reset in noCarrier()
TGID and SRC were not displaying for X2-TDMA frames
Fixed buffer issue in resumeScan()
Fixed error in .wav file headers preventing playback on some apps
1.3 New features:
Decodes voice from ProVoice signals (requires -fp option)
algid and kid are now shown in hex notation

Fixed bugs:
nac was showing wrong ID
p25 metadata (lcinfo, mfid, lfcormat, mi, keyid, algid, lsd) are now
P25 metadata (lcinfo, mfid, lfcormat, mi, keyid, algid, lsd) are now
