A simple web browser for beqcatalogue which integrates with minidsp-rs for local remote control of a minidsp or HTP-1.
Python is required so use an appropriate package manager to install it.
chocolatey is a convenient choice for Windows homebrew is the equivalent for MacOS
Use your distro package manager to install python.
Example is provided for rpi users
$ ssh pi@myrpi
$ sudo apt install python3 python3-venv python3-pip libyaml-dev
$ mkdir python
$ cd python
$ python3 -m venv ezbeq
$ cd ezbeq
$ . bin/activate
$ pip install ezbeq

See the configuration section below
$ ssh pi@myrpi
$ cd python/ezbeq

$ pip install --upgrade --force-reinstall ezbeq
then restart the app
$ ssh pi@myrpi

Loading config from /home/pi/.ezbeq/ezbeq.yml
2021-01-16 08:43:15,374 - twisted - INFO - __init__ - Serving ui from /home/pi/python/ezbeq/lib/python3.8/site-packages/ezbeq/ui
Now open http://youripaddress:8080/index.html in your browser
See $HOME/.ezbeq/ezbeq.yml
The only intended option for override is the port option which sets the port the UI and API is accessible on. This defaults to 8080.
If catalogueUrl is added to the configuration, e.g.
catalogueUrl: http://localhost:9999
ezbeq will instead load the catalogue from http://localhost:9999/database.json
This provides the ability to run ezbeq against a custom, or locally provided, catalogue.
The devices section contains a list of supported device, the format varies by the type of device and each item is a named device with the name subsequently appearing the UI (if multiple devices are listed)
Default values are shown, the only required value is the type field
minidsp:
cmdTimeout: 10
exe: minidsp
ignoreRetcode: false
options: ''
slotChangeDelay: false
type: minidsp
By default, it is assumed the Minidsp 2x4HD is in use. To use a different model, specify via the device_type option. For example:
minidsp:
cmdTimeout: 10
exe: minidsp
ignoreRetcode: false
options: ''
type: minidsp
device_type: 4x10
In order for the ezbeq ui to update when the device status is updated outside of ezbeq (e.g. using minidsp remote control), additional configuration is required to enable the minidsp rs websocket interface
This requires 2 optional additional values in the configuration
wsDeviceId: 0
wsIp: 127.0.0.1:5380
wsIp is the address of the [http_server] from /etc/minidsp/config.toml
wsDeviceId is the device id provided by minidsp probe, in this example 2 device ids (0 and 1) are available
$ minidsp probe
Found 2x4HD with serial 911111 at ws://localhost/devices/0/ws [hw_id: 10, dsp_version: 100]
Found 2x4HD with serial 911112 at ws://localhost/devices/1/ws [hw_id: 10, dsp_version: 100]
Using, and controlling, multiple devices independently is supported but does require use of the options key in order to direct commands to the right device. Precise configuration of this option depends on the minidsp-rs setup so is out of scope of this readme. Typical configuration would involve use of the --tcp option combined with changes to minidsp.toml as mentioned in the minidsp-rs docs.
For reference, a community provided example configuration guide can be found via avs
By default, the slots are numbered 1-4 as per the minidsp console.
To override, extend the device configuration with the slotNames key as illustrated in this example. It is not necessary to list every slot, just those that require an explicit name.
Device support largely tracks minidsp-rs device support.
BEQ MV adjustments are applied to input peq channels only.
set device_type: 24HD
BEQ filters are written to both input channels.
configure as per 2x4HD
add slotChangeDelay: true to workaround issues with slow slot changing. If it remains unstable, use slotChangeDelay: 1.5 (or some other number, experiment to find the smallest value that enables a reliable experience).
Dirac mode (PEQ on output) is only supported at present via a custom configuration.
set device_type: DDRC24
BEQ filters are written to all output channels.
set device_type: DDRC88
BEQ filters are written to output channel 3 by default.
Add the sw_channels config key to override this, provide a list of channel indexes (0 based) to which the filters should be written. For example to write to the last two output channels:
device_type: DDRC88
sw_channels:
- 6
- 7
requires minidsp-rs 0.1.12 or later
set device_type: HTx
BEQ filters are written to output channel 3 by default.
Add the sw_channels config key to override this, provide a list of channel indexes (0 based) to which the filters should be written. For example to write to the last two output channels:
device_type: DDRC88
sw_channels:
- 6
- 7
set device_type: 4x10
The limited biquad capacity (5 per channel) means that filters are split across input and output channels and there is no capacity for user filters.
set device_type: 10x10
The limited biquad capacity (6 per channel) means that filters are split across input and output channels and the last 2 biquads per output channel are left under user control.
To avoid this, use the crossover biquads to hold the remaining beq biquads. This leaves the output PEQ untouched. Set use_xo to one of the following values to activate this mode:
set device_type: SHD
BEQ filters are written to all output channels.
set device_type: 8x12CDSP
BEQ filters are written to all 6 input channels.

Q-Sys Designer is supported via the QRC protocol

Configuration of the audio pipeline in Q-Sys Designer is left as an exercise for the user.
2 alternative implementations are possible.
One uses a IIR Custom Filter component which must be connected to component which provides a text field.
This can be implemented using either a Text Controller or a Custom Control.
This component allows for a mapping of a text field control key to a CatalogueEntry field name.
Two fields have special treatment:
The alternative approache uses a Parametric Equaliser component which should be configured with:
The component name should be supplied in the configuration above.
Note that this format does not support variable Q shelf filters.
CamillaDSP is supported via its websocket api which means CamillaDSP must be started with additional options:
-p to specify the port-a to specify the listen address (required if ezbeq runs on a different host to camilladsp) camilla:

On load, the camilladsp configuration will be updated as follows:
Filters section in IIR format using one of the Peaking, HighShelf or LowShelf filter types. Filter names will be BEQ1 to BEQ10Filter will be added if not already present for that channelOn unload, the camilladsp configuration will be updated as follows:
Filters sectionPipeline sectionUser controlled master volume adjustments are supported using the Volume filter if that filter has been configured in the pipeline.
BEQ specific input gain adjustments are supported via the use of a Gain filter which is inserted into the pipeline ahead of the BEQ filters themselves.
This is optional but recommended, it ensures the app starts automatically whenever the rpi boots up and makes sure it restarts automatically if it ever crashes.
We will achieve this by creating and enabling a systemd service.
