IT'S NOT ALWAYS WHAT YOU THINK

I thought I might post this simply because I was reminded a week or so ago that it's not ALWAYS going to be the "go to" mic that does the job.

I have a bunch of mic choices. Lrg D condensers, sml D condensers, lrg D dynamics etc etc..AND a bunch of different mic preamps to hook these up to. In short, a decent selection and tool box that I know how to use for most situations.

DSP choice

Hello everybody,

My application aims for Active Noise Cancellation, I have to use Microphones and a DSP to digitize the received signal then act on speakers to cancel the noise.

Could you please help me on which criteria that i have to put into account in order to choose the right DSP, and if you have any suggestions concerning DSP evaluation boards ?

Reverb

Reverberation, in psychoacoustics and acoustics, is the persistence of sound after a sound is produced. A reverberation, or reverb, is created when a sound or signal is reflected causing a large number of reflections to build up and then decay as the sound is absorbed by the surfaces of objects in the space – which could include furniture, people, and air.

Plate Reverb

A plate reverb system uses an electromechanical transducer, similar to the driver in a loudspeaker, to create vibrations in a large plate of sheet metal. The plate’s motion is picked up by one or more contact microphones whose output is an audio signal which may be added to the original "dry" signal.

Spring Reverb

A spring reverb system uses a transducer at one end of a spring and a pickup at the other, similar to those used in plate reverbs, to create and capture vibrations within a metal spring. Laurens Hammond was granted a patent on a spring-based mechanical reverberation system in 1939.
