Transferring settings from Lake

Hi Eclipse Audio,

We have a number of loudspeakers with profiles for Lake processing (LM and PLM) and are wanting to use them on some of our other DSP enabled amplifiers.

Is it possible to use Eclipse Audio FIR Designer (M) / Creator (EX) to import a Lake profile and convert and export the FIR and IIR filters to a Powersoft or Linea Research amplifier platform?

If this is possible what tier of the software is required for this functionality?

1. Importing
Our products can’t automatically import settings and presets. IIR filter settings need to manually entered in the ‘IIR Filters’ tab. Existing FIR filters (if you have them) can’t be loaded in the main workflow, but can be side-loaded when pushing settings to some brands, via their branded DTP windows in our products; specifically Marani, Lake, Lab Gruppen and Powersoft. When side-loading the existing FIR filters, they don’t need to be same length and sample rate as the target DSP – the software can sample rate convert and rewindow the filters, if needed.

2. Lake: locked module
Most loudspeaker manufacturers (supplying Lake modules) lock the Lake modules so that you can’t see the IIR & FIR filters (including crossovers). If this is the case, you will need to measure the transfer function for each output channel (of the multi-way module) using a Lake Processor or Lake amplifier (like a PLM) into dummy loads at low to moderate levels. (Remember when measuring, to use a dual-FFT approach, comparing the channel being measured with another channel, which another module, that has no settings. This measurement will also have the channel delay, in the transfer function, so if you set the measurement alignment delay to anything other than 0, make a note of the alignment delay, as you’ll need it in the final preset for Powersoft or Linea Research.

3. Lake: unlocked module
If the Lake module is not locked, you can copy the IIR filter settings manually from the Lake Controller – you may need to be in Designer mode – into FIR Designer’s ‘IIR Filters’ tab and immediately convert the settings to Powersoft or Linea Research. There is no way to extract the FIR filter directly – if the Lake module uses them. It can only be done from measurement.

4. Target measurements
If the module is locked and you only have a TF measurement for each channel, the TF measurement can be loaded into the ‘Target’ tab in our products, then you can use the rest of the workflow to create IIR + FIR filter settings to match the Target. Do this once for each output channel.

If the module is unlocked and you have both IIR filter settings and a TF measurement, load the TF measurement on the ‘Target’ tab and enter all the IIR filters into the ‘IIR Filters’ tab. If the Lake module doesn’t use FIR filters, then the ‘IIR Filters’ tab response should match the TF measurement. If there are any differences, then you can continue through the workflow to make a FIR filter as well.

5. Which Eclipse Audio products?
FIR Designer and FIR Designer M have the IIR filter conversion across brands. FIR Designer is a single channel product and can be used to do the conversion you need, with one FIR Designer project per channel. FIR Designer M is a multi-way product and can be used as well, but it’s more than you need for this conversion work.

I’d suggest downloading a demo version of FIR Designer and watching the overview video to understand the workflow.

6. Limiters
Our products generally don’t deal with limiter settings. You’ll need to figure out how to translate Lake limiter settings into Powersoft and Linea Research. Again, Lake limiter settings are usually completely hidden (for locked modules) or hidden in ‘Designer mode’ ‘Factory settings’, for unlocked modules. Note that output channel delay and level settings are also often hidden in the same way. (FIR Designer M can push limiter settings to the Lake XP modules, but you need to know then in advance.)
