MiniDSP Command-line interface

This provides a command line interface to control MiniDSP devices. It's a complete rewrite from node-minidsp and aims to support multiple devices. Feel free to open an issue if you have access to other hardware!

Installation

cargo install minidsp

Usage

USAGE:
    minidsp [OPTIONS] [SUBCOMMAND]

FLAGS:
    -h, --help       Prints help information
    -V, --version    Prints version information

OPTIONS:
        --tcp <tcp>    The target address of the server component
        --usb <usb>...    The USB vendor and product id (2752:0011 for the 2x4HD)

SUBCOMMANDS:
    config    Set the current active configuration,
    debug     Low-level debug utilities
    gain      Set the master output gain [-127, 0]
    help      Prints this message or the help of the given subcommand(s)
    input     Control settings regarding input channels
    mute      Set the master mute status
    output    Control settings regarding output channels
    probe     Try to find reachable devices
    server    Launch a server usable with `--tcp`, the mobile application, and the official
              client
    source    Set the active input sourcee

Running without arguments will print information about the current state:

$ minidsp 
MasterStatus { preset: 0, source: Toslink, volume: Gain(-36.5), mute: false }
Input levels: -131.4, -131.4
Output levels: -168.0, -168.0, -120.0, -120.0

Commands are organized in different categories:

Commands changing global state

# Set input source to toslink
minidsp source toslink

# Set master volume to -30dB
minidsp gain -- -30

# Activate the 2nd configuration setting (indexing starts at 0)
minidsp config 1

Input channel configuration

minidsp input For more details, look at minidsp input --help

Examples

# Sets input channel 0's gain to -10dB
minidsp input 0 gain -- -10

# Mute input channel 0
minidsp input 0 mute on

# Route input channel 0 to output channel 0, boost gain by 6dB
minidsp input 0 routing 0 enable on
minidsp input 0 routing 0 gain 6

# Bypass the first PEQ on input channel 1
minidsp input 1 peq 0 bypass on

Output channel configuration

>  minidsp output <output-index> <SUBCOMMAND>
> For more details, look at `minidsp output --help`

Examples

# Set the delay on output channel 0 to 0.10ms
minidsp output 0 delay 0.10

# Mute output channel 1 
minidsp output 1 mute on

# Invert output channel 1's phase
minidsp output 1 invert on

# Bypass the first PEQ on output channel 1
minidsp input 1 peq 0 bypass on

udev

In order to run as a non-privileged user under Linux, you may have to add a udev rule for this specific device. Under /etc/udev/rules.d, create a file named 99-minidsp.rules containing:

# MiniDSP 2x4HD
ATTR{idVendor}=="2752", ATTR{idProduct}=="0011", MODE="660", GROUP="plugdev"

Then reload using:

sudo udevadm control --reload-rules
