This library works hand-in-hand with the Audio Equalizer Filtering Library, which does the actual signal processing (filtering). Graphic Equalizers are used to adjust the spectral content of music by providing gain or attenuation to parts of the music based on frequency. The Graphic Equalizer Display Library works on any Microchip device that drives an LCD display, providing Graphic Equalizer displays for the host application. O Used for user preference filtering and real-time gain adjustment per frequency band O Typically runs band-pass filter designs O Parallel architecture of filters, 2 biquad filters per band, summed for a single output O Used for factory tuning of speaker and enclosure / environmental harmonics O Typically runs peaking and shelving filter designs
AUDIO EQUALIZER SOFTWARE SERIAL
O Serial sequence of IIR filters from 2-20 biquads It supports filter architectures for traditional graphical equalization and for parametric equalization. The library provides filtering primitives for audio equalization using infinite impulse response (IIR) filters. An audio equalizer filtering library performs various tasks including digital filtering to correct deficits in the recorded music, mitigate problems in the speakers being used, or simply correct for the room's acoustics - all focused on improving the user's experience of the music. In music playback, digital filtering can be performed before digital bits are converted into analog voltages that are played by speakers to maintain high fidelity audio as shown in the figure 1 above.
AUDIO EQUALIZER SOFTWARE BLUETOOTH
Bluetooth audio speakers & audio peripherals.The library can support either graphic equalizer or parametric equalizer filtering functions.Īn optional element of graphical frequency-band magnitude is also available to enable a real-time display of the audio output.
The library can work from multiple audio sources, and customize the listening experience to compensate for speaker, room / enclosure acoustics or user preferences. The PIC32 Audio Equalizer (EQ) Filter Library is specifically designed to assist with multiple-frequency filtering of digital audio.
