Hi Phil.
cheers for that.
Please excuse my stupidity, but what's a reverb impulse?
Phil replied: an impulse file is a file that has captured a space such as a
room, or hardware such as a Lexicon LXP1. These files can be loaded into
convolution software such as PerfectSpace that ships with Sonar. This can
then be added to a bus. They sound much more realistic than normal software
such as the Lexicon reverb that ships with Sonar. You can get impulse files
for bass amps, acoustic guitars, compressors etc. You can load wave files into
PerfectSpace, as well as some other formats. Here's some information from the
PerfectSpace Manual.
"The process of convolution allows you to apply the acoustic characteristics of
any space to any input signal. These acoustic characteristics are captured
within audio files called impulse responses.
An impulse response can specifically represent a certain location, from a
famous cathedral to a locker room shower. Impulse responses (IRs) are created
by recording the reverberations within these spaces after playing special tone
sweeps or firing a starter pistol. These wideband "impulse" sounds typically
span the entire audible frequency range, so the recorded "response" includes a
complete representation of how the space reacts to all frequencies. Use IRs of
this type to change your project's performance location without moving an inch.
Convolution is not limited to emulating pre-existing spaces, though. In fact,
you can use absolutely any sound (drums, claps, screams, towel snaps, etc.) to
manipulate your source audio. With creative convolving, you can achieve very
interesting filter, reverb and delay effects."
