A. Modules

To improve flexibility, we have organized the upcoming online EASE® training in a series of modules that can be configured in different ways to cover the topics needed by the attendee. See a description of each module below.

AFMG Loudspeaker Data Authorization – Key Factor for Successful Market Placement

In view of the general economic crisis caused by the Covid-19 pandemic, AFMG® recognizes the need of many customers for investment relief in licensing the EASE Focus 3, EASE Address, and AFMG FIRmaker software solutions. These are considered a key factor for successful product placement and growth. For this reason, AFMG introduces a new investment support program that includes installment payments and a 15% discount.

How to Implement and Sign a GLL Plug-In ?

API Implementation and GLL Plug-In Signing Overview

Within your subscription you will always receive the latest AFMG SDK for the GLL Plug-In API. This Software Development Kit contains all current API libraries and information on how to implement them in order to develop your own GLL Plug-Ins.

Creating GLL Plug-Ins is straightforward. In the following a technical overview of this process is given.

How do the FIR filter coefficients get from FIRmaker into the DSP?

Since the implementation of FIRmaker will be done individually for each loudspeaker system and in close partnership with each loudspeaker manufacturer, the DSP controller platform/software will need to integrate closely with FIRmaker as well. Different levels of integration are possible, depending on the loudspeaker systems in use and the degree of usability manufacturers want to present to their users:

How can DSP/amplifier manufacturers enhance the integration of their DSPs with FIRmaker?

AFMG SDK for DSP Communication Service

In order to facilitate the transfer of FIR filters to third party DSP software, AFMG provides manufacturers with an SDK for our DSP Communication Service. With this software development kit, the DSP manufacturer is able to develop its own server module that automates the communication with EASE Focus 3. This functionality significantlyspeeds up the work of sound system designers and consultants.

How many FIR taps does FIRmaker need? What is the latency of FIRmaker processing?

Various simulations and experiments have been carried out by AFMG. So far results indicate that a minimum of 250 taps at 48 kHz is required in order to achieve good performance for the majority of use cases. A number of 500 to 1000 taps are recommended for complicated setups.

Processing of 250 FIR coefficients at 48 kHz corresponds to 5 ms of latency.

Does FIRmaker optimization with only one FIR channel per cabinet work in practice?

It certainly does! — Field tests (some of which have already been published by AFMG) indicate that substantial performance improvements can already be achieved when using only one FIR channel per cabinet. The explanation is simply that the sound waves in the mid-frequency range have wave lengths of the order of the cabinet spacing in typical line arrays. It is not necessary to have a much higher resolution than that.

How many FIR channels make sense for my system?

FIRmaker can work on any level: FIR processing can be applied to individual transducers in a cabinet, to groups of transducers, to entire cabinets or to groups of cabinets (e.g. pairs).

For many practical applications one FIR-channel per cabinet seems to provide a good compromise between improved sound quality and required processing power. In principle, the optimized performance of the line array is determined by the spatial resolution of the sound sources to which FIR processing is applied.
