This sound is a 1-sample long impulse at 48 kHz.
It covers the whole frequency range with equal power.

This is a perfect sample for exciting your guitar amp or reverb unit to capture it's impulse response (IR). You can also play it through a speaker in a reverbant room to capture it's reverb characteristics. Remember that the IR sample will be no flatter than your speaker's performance multiplied by your microphone's performance (frequency response characteristics).

The sample has exaclty 1 second of silence, then the impulse, then another second of silence to ensure the impulse will be played clean and untruncated on any sound system or device.

My test with IR LV2 convolution plugin have proven, that this sample has absolutely flat frequency response - convolved signal was identical to the source signal. After normalization and sample-alignment of the sound clips I have inverted the polarisatin of one of them and summed them - result was absolute silence, even no hiss was present as a result. This shows the accuracy of the convolution process and proves this sound to be perfect for sampling IR.

The impusle was generated with C* Dirac LADSPA plugin.
Created using Audacity.
