# smplay(1)

Program to play a SpectMorph model

## NAME

smplay - Program to play a SpectMorph model

## SYNOPSIS

**smplay** \[*OPTIONS*\] *SM-File\|SMSet-File*

## DESCRIPTION

**smplay** is a command line based player for SpectMorph models (which can be created using **smenc**). Playing can use the audio card, so that the model will be heard directly, or create a wav file instead if the **--export** option is used.

Since the SpectMorph model consists of sine waves and noise, options to disable one of these components exist.

## OPTIONS

**smplay** follows the usual GNU command line syntax, with long options starting with two dashes ('-').

- **-h**, **--help**

  Shows a brief help message.

- **-v**, **--version**

  Prints out **smplay** version.

- **--rate** *\<sampling rate\>*

  Set replay rate manually; also useful for specifying the desired rate of the wav file, if **--export** is used.

- **--no-noise**

  Disable noise decoder, so that only the sine wave part of the signal is decoded.

- **--no-sines**

  Disable sine decoder, so that only the noise part of the signal is decoded.

- **--det-random**

  Use deterministic random generator; this will produce identical noise components if the same file is decoded twice, making the audio output exactly the same.

- **--export** *\<wav filename\>*

  Instead of playing the file, write the output to a wav file.

- **-m**, **--midi-note** *\<note\>*

  Select midi note to play, in case an SMSet-File was specified as input file.
