SYNOPSIS

sonivoxrender [-h|--help] [-v|--version] [-d|--dls file.dls] [-r|--reverb 0..4] [-w|--wet 0..32767] [-n|--dry 0..32767] [-c|--chorus 0..4] [-l|--level 0..32767] [-g|--gain 0..100] [-V|--Verbosity 0..5] midi_file

DESCRIPTION

This program is a MIDI file renderer based on the sonivox synthesizer library. It reads .MID (Standard MIDI Files) file format, and writes an audio stream to the standard output as raw 16 bit stereo PCM samples.

  Options

-h, --help
    Prints brief usage information.

-v, --version
    Prints the version numbers.

-d, --dls file.dls
    Optional DLS soundfont file name. If not provided, it uses an internal embedded soundfont.

-r, --reverb reverb_preset
    Reverb preset between 0 and 4: 0=no, 1=large hall, 2=hall, 3=chamber, 4=room.

-w, --wet reverb_wet
    Reverb wet level between 0 and 32767.

-n, --dry reverb_dry
    Reverb dry level between 0 and 32767.

-c, --chorus chorus_preset
    Chorus preset between 0 and 4: 0=no, 1..4=presets.

-l, --level chorus_level
    Chorus level between 0 and 32767.

-g, --gain master_gain
    Master gain between 0 and 100, default is 90 (10 dB below maximum).

-V, --Verbosity verbosity
    Verbosity level between 0 and 5, where 0=no, 1..5=severity levels.

  Arguments

midi_file
    Input MID file name.

EXAMPLES

The following examples assume the default option USE_44KHZ=ON, which means an output sample rate = 44100 Hz.

Example 1: Render a MIDI file and save the rendered audio as a raw audio file:

    $ sonivoxrender ants.mid > ants.pcm

Example 2: pipe the rendered audio thru the Linux ALSA aplay utility:

    $ sonivoxrender ants.mid | aplay -c 2 -f S16_LE -r 44100

is equivalent to:

    $ sonivoxrender ants.mid | aplay -f cd

Example 3: pipe the rendered audio thru the lame utility creating a MP3 file:

    $ sonivoxrender ants.mid | lame -r -s 44100 - ants.mp3

Example 4: pipe the rendered audio thru the sox utility creating a WAV file:

    $ sonivoxrender ants.mid | sox -t s16 -c 2 -r 44100 - ants.wav

Example 5: pipe the rendered audio thru the PulseAudio’s pacat utility:

    $ sonivoxrender ants.mid | pacat
