About Alango Music Refiner package (MuRefinerô)

MuRefiner is a set of integrated DSP technologies for music and entertainment applications enhancing user audio experience. The full package includes the following components:

Figure 1. Alango MuRefiner DSP blocks scheme

 

Stereo normalizer – improves perceived stereo effect by dynamically optimizing (widening or narrowing) stereo image according to user preferences, listening environment and the audio signal. The audio content is analyzed in real time increasing stereo depth of “flat” recordings while shrinking too wide stereo of others providing equally pleasant music listening with loudspeakers or headphones.

Spectral compander – adds details and brightness to the sound by reducing short-time spectral variance. Weak frequency regions are dynamically amplified increasing perceived brightness of audio while even small nuances and passages are being kept and emphasized.

Bass corrector – creates deeper, richer sound by boosting up bass line simultaneously performing bass limitation preventing sound from saturation and overloading the speaker and power amplifier.

Frequency equalizer – optimizes frequency response for specific speakers/headphones allowing defining different presets for various types of music.

AVQ-Me  (automatic volume and equalization control, optional) - amplifies and equalizes sound according to ambient noise characteristics providing equal perceptual loudness, intelligibility and sound coloration in conditions where noise level and spectrum are changing dynamically (refer to AVQ-Me technology description)

WINAMP MuRefiner™ DSP plugin integrates the following components: stereo normalizer, spectral compander, bass corrector

MuRefiner is available on embedded DSP platforms. Please contact Alango for more information.
