This can be tolerated to a peak level difference of 4dB between center and left output. However, that microphone faces the center stage speaker on-axis so it is brighter, and its path is shorter so it is louder. We originally decided to use a front row center microphone for that. Left and right microphones are typically spaced by more than 3 meters.įor Altiverb 8 we needed to select a center output to the front L and R microphones in every room. ![]() We use widely spaced omnidirectional microphone setups to capture the IR. With the Stage Positioning turned On the Center channel now better equals Left and Right channels in a number of rooms. Version 8.0.7 chooses a better fitting center channel for a number of rooms. Please note that all of the above only applies to Altiverb 7 settings received by Altiverb 8. Similar measures have been taken in the quad input quad output and the 5.1 input 5.1 output instances. In Altiverb 8 5.0 input to 5.0 output Altiverb 7 settings are loaded with 60% cloud size, which may result in a higher output level than in Altiverb 7 produced, depending on different circumstances. When cloud size is increased it gradually adds speakers which increases the total level. One should be available for most Impulse Responses in the Altiverb collection. You may, as we do, prefer the native Altiverb 8 way: if you have just upgraded to v8 when opening your Altiverb 7 project or template we advise you to open your Altiverb 5.0 input to 5.0 output instances and load the true 5.0 Impulse Response in there. Altiverb 8 will load the IR that was chosen in Altiverb 7, including the center bleed. Center reverb was created via the center bleed option, a delayed mix of the rear channels in the front. In a 5.0 input to 5.0 output instance of Altiverb 7 a stereo to quad output IR was loaded by default, mainly because no 5.0 IRs existed in Altiverb 7. The 5.0-in 5.0-out Altiverb 8 loads new true 5.0 IRs by default, implements easy center-channel-only reverb with input pan following and adjustable cloud size.įor Post this instance has undergone massive improvements and it was the most challenging to keep it backward compatible. The 5.0-in 5.0-out Altiverb, however is mainly targeting post. Levels are improved in Backward compatibility situations for the Altiverb 7 instances with input-output: quad to quad, 5.0 to 5.0 and 5.1 to 5.1.Īltiverb is a music and post reverb. Color is adjusted between neutral (flat) and the actual direct sound that is in the Impulse Response (IR), which sounds more realistic, but can give unwanted coloration as it can contain a very early reflection from an on stage piano or the stage itself, and also includes speaker and microphone coloration.Įarly and tail can be switched on or off and the levels can be changed too. The gain and color of the direct sound can be adjusted. The four knobs on the right manipulate the different stages of the impulse response, starting with the earliest part: the direct sound. A demo of this is in the first minutes of the Altiverb 8 guided tour video. You should use it fully wet, but even then you hear quite some dry-ish material, because there is a direct path from speakers to microphones. This is the absolute most realistic sounding virtual playback of your audio in any space in Altiverb. You can also, right there, move the speaker around. Using the positioner tab, available only in mono and stereo input Altiverbs, you can switch on the speaker, in which case you can hear where it stands. So there is a direct relation between the amount of inputs and the speakers used. When making impulse responses, we used either one speaker position in the center of the stage for mono input, or two speaker positions for stereo input. ![]() Do not playback loud, to protect the people around you, and do not record loud to make sure you don’t clip the recording.Īltiverb can have mono or stereo inputs.all of these measures will increase the low end in a more complex and natural way than post-eq. If you feel the result sounds too thin, try a speaker with bass reflex ports on its front, or a bigger speaker, or change out directional microphones for omnidirectional microphones. Neutral is crucial if you want to reverberate dialogue and match it to something real. ![]() Few speakers when free standing like in the video, sound neutral on-axis at a couple of meters distance. You will find your speaker to be the most critical component.Decide if you would be satisfied if that were Altiverb. To test your setup on the location: play dry music through your speaker and compare the recording in the room to the dry recording. ![]() Carefully measure that everything is symmetrical, with large setups, a large error is easily made.Space the microphones far apart, several meters if possible.
