Tech Focus: Wheatstone offers audio processing for streaming

Tech Focus: Wheatstone Streamblade and Wheatstream appliances use audio processing techniques designed specifically for streaming to optimize performance and achieve the best sound across even the lowest bitrates. Unlike other techniques that can cause distortion, Wheatstone streaming appliances use RMS density algorithms as part of a five-band intelligent AGC to smooth out source transitions and feed a steady diet of consistent audio levels.

Also unique to Streamblade/Wheatstream is a two-band final limiter section that removes hard limiting or clipping from the processing chain yet keeps programming within the codec’s 0 dBFS limit. As a WheatNet IP audio network appliance or as an addition to any network, these streaming appliances also have a stereo width management section that eliminates the big swings in dynamic L-R that can skew the codec algorithm at the expense of quality programming, plus bass boost and monaural bass features for optimizing low bitrate streams.

A two-stage phase rotator that corrects voice asymmetry and removes noise and hum and a four-band parametric equalizer with peak and shelf functions help stream the best quality possible at various bitrates.
