Material Color versus Face Color
What is the difference between Material Color and Face Color?
Level and Delay for Auralisation Files
How can I handle in EASE/EARS signals (WAV files) which have different levels and onset times (delays) ?
Real-Time Source for Convolution/Auralisation
My CD player works fine with my full-duplex sound card. When I want to play it through the realtime Lake convolver, there is no signal at the convolver. What is wrong?
Message "Convolver Error 1: General Error"
CD playback with the Lake Convolver results in the error message 'Convolver Error 1: General Error'. The CD player itself does work. What does that mean?
There can be many different causes for this error. Most probably, however, is an installation problem related to your sound card and/or audio mixer.
Does the Lake convolver on your PC work fine with
Lake Convolver not convolving?
When I convolve my FIR filter file with a wav file as the source and play it thru my speakers, the EARS convolver gives me what I would expect, and the Lake sounds like just the source (input) wav file.
Switch on [x] Convolve in the FIR Filter Frame. If off, Lake works as player. The EARS convolver sets this switch itself. Does the peak level indicator go to color? If not, you are in play mode
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. The module uses responses computed either with EASE Standard or EASE Standard including the AURA module.
