So been experimenting a LOT with adding in audio-tactile with SSW.
Generally getting good results with specific EQ being applied to each car.
What we need is the ability to have the tactile responed for the mid-high RPM values and these have a suitable strongish frequency to add to the immersion. Often the audio itself with many (yet not all cars) is lacking usage of mid-low bass frequencies with the high RPM values.
I even went back to have a look at "Engine Beat" effect (3).
On testing part of a configuration for some members on the forums. I did actually get a rather decent feeling from this on testing a seat using the full-size BK-LFE (seat base) and a Clark TST 329 (seat spine). High end models yes but many users are buying higher quality tactile hardware.
These devices are installed on the seat to operate as one for low bass and the other mid-high bass frequencies. This works well with the "audio-tactile" and engines.
Some Tinkering:
I set in Audacity for Cen/Sub channels (these units are on) two generated tones.
48Hz for the TST on channel 3
24Hz for the LFE on channel 4
Now this helped the "repeated thump" sensation "Engine Beat" has with a single repeated tone.
Having 2 cycles on the TST for each one on the LFE both felt in the seat was not that bad and felt more natural...
However having this represent engine idle and fade out as speed progress is the opposite of what we need. The reason being many cars generate quite sufficient and some rather good "engine idle" and "low RPM" from the audio.
What we need is the higher RPM values that are used constantly with gear changes to have felt sensation. To represent "engine load" and chassis vibration sensation.
Andre can you please consider in the Beta version, even for a test, alter when engine beat operates. Rather than it operating from idle have it operate from 30% full RPM value. If it can also alter with an increase in amplitude as the RPM gets higher, that would perhaps be a good step forward...
Seen this and thought you might like it, thanks for your efforts thus far.
