Convolution Impulses

These are 24-bit 44.1 kHz stereo recordings of acoustic impulses, for use with convolution software such as the excellent freeware SIR. They were made with a pair of large-diaphragm condenser mics.

The Dining Room impulse has had the initial impulse removed so you can use it as usual: mixing in the desired amount of wet (reverberation).

However, I have not removed the initial impulse from the instrument impulses. The theory is that you should process through the complete impulse and use the all-wet results. For example, applying the complete acoustic guitar impulse to an electric guitar signal gives the effect of playing through the bridge/body of an acoustic guitar. Of course, it is impossible to recreate the string noise with this technique; you may wish to mic your electric guitar and mix in some of this acoustic string noise for a brighter sound. Or experiment with chopping the initial impulse and/or mixing some of the dry signal in.

Acoustic Guitar

Impulse was a sharp tap on the bridge with a ceramic spoon. I did not remove the initial impulse.

String Bass

Impulse was a sharp tap on the bridge with a ceramic spoon. I did not remove the initial impulse.

Upright Piano - Undamped

Impulse was a sharp tap on the soundboard with a ceramic spoon. This recording has the damper down.

Upright Piano - Damped

This is the damped (damper up) recording only, which is a much smaller download due to the shorter reverberation time.

Upright Piano Strings

This is the effect of banging on the strings directly. This might be useful as a special effect...

Dining Room

Small, live, irregularly-shaped dining room. Impulse was a balloon pop. I removed the initial impulse, so you can use this as a reverb and adjust the wet/dry level conventionally.
