Lake Convolver Peak Gain
Using the Lake Convolver: if a .BIR filter is added, the 'Peak Gain' button does not adjust the 'Gain [dB]' until after the filter has been installed and playback has been started.
Lake Convolver in the Background
The audio playback using the Lake Convolver is muted whenever the focus changes to another window. It returns when the focus is returned to the convolver DB.
Yes, the Lake convolver strictly needs an open and active window. You can relax the problem with 'Ears/Utilities/Auto Foreground' on. Then EARS pulls back the focus automatically after you have clicked somewhere else.
Menu Items "Keep to Auralize" and "Keep as Start Default"
What are the menu options 'Keep to Auralize' and 'Keep as Start Default' under Ears/Utilities used for?
Level and Delay for Mixing Files
I have produced different WAV files by the Lake convolver for further processing with the Ears WAV Mixer. How can I get their proper SPL and delay values?
The Lake convolver is designed for real-time listening. For manipulation of convolved signals we recommend the use of the EARS convolver. It automatically produces WAV files with proper level and delay information.
When is it recommended to use the EARS module to perform auralization?
The EARS module is a post-processing program that adds the ability to perform auralizations of a room, allowing you to hear how it will sound with the best approximation available in the market.
AURA Simulation Parameters - what should I use when?
AURA is a highly sophisticated room-acoustic module. It has been integrated into EASE, based on the CAESAR software from Aachen University. It can be considered as consisting of two different engines. One method is utilized for highly accurate auralisations at selected receiver positions, it is called AURA Response. The other one is less precise but much faster and therefore allows for the calculation at many points, that means AURA Mapping.
Can I use the same GLL loudspeaker file in all AFMG modeling programs?
Not all GLL files are the same. Some AFMG® programs have specific requirements for a GLL in order that the program is permitted to use the GLL.
1. GLL Types
The chart below summarizes what types of GLLs can be used in each AFMG program.
We are a loudspeaker company. Do you have measurement guidelines for creating loudspeaker data files in GLL format?
Accurate loudspeaker data is necessary for reliable simulation results.
As a manufacturer you can measure and create loudspeaker data yourself. In addition to the proper equipment, you would need in-depth knowledge about the measurement techniques to adequately model the loudspeaker behavior. For this please refer to SpeakerLab’s comprehensive User´s Guide which can be found under the link below.
