BusinessPhone Communication Platform 4.0
VMU-HD & MFU

## General Information

The PC-program WAV2VMU.EXE (LZY 203 2248) converts audiofiles from WAV to VMU format for VMU-HD and MFU.

Usage:

    WAV2VMU <filename[.WAV]> /option1 /option2

Options:

/A |  | cuts the files after a block, if the signal is < -45dB

/C |  | cuts frequencies below 250 Hertz

/L |  | converts to VMU-HD / MFU low quality format (high quality is default)

/N |  | no cutting. If necessary, silence is added.

/+ |  | output file +6 dB

Recording the voice prompts the name of the <filename[.WAV]> should be according to the lists in this document (see following pages).

E.g.: The voice prompt “I am absent at the moment and will be back at” should be recorded as D031D031.wav and will be converted and renamed by the program to D031D031.001.

After a successful conversion a file with one of the following names will be created:

- <filename>.000 Voice storage capacity: VMU-HD / MFU Low Quality (32 Kbits/sec.) or
- <filename>.001 Voice storage capacity: VMU-HD / MFU High Quality (64 Kbits/sec.) (= default value)

#### Limitations

- Wildcards in <filename> are not allowed.
- Only certain WAV formats will be supported:

- 8 or 16 bit samples
- mono or stereo
- 11.025 kHz, 22.05 kHz or 44.1 kHz sample rate

- Not supported:

- 4 bit & 12 bit samples
- all kind of audio codes (compressed formats)

#### PCMCIA
