ALC5624 datasheet hand-held multimedia i 2 s audio codec 21 track id: jatr-1076-21 rev. 1.3 7.10. hardware sound effects the sound effect block is composed of pseudo ster eo, spatial 3d, and equalizer blocks. the pseudo stereo block is used to convert a mono source into virtualized stereo output. the spatial 3d block is a surround sound generator with adjustab le amplitude (gain) and surroun d depth (ratio). the equalizer block can be used to compensate fo r speaker response, or to make e nvironment sound effects, e.g., ?pub?, ?live?, ?rock?,? etc.. 7.10.1. equalizer block the equalizer block cascades 5 bands of equalizer to compensate for speaker response and to emulate environment sound. one high-pass filter cascaded in the front end is used to drop low frequency tone, which has a larger amplitude and may damage a mini speaker. the high-pass filter can also be used to adjust treble strength with ga in control. a low-pass filter with gain control can adjust the bass strength. three bands of bi-quad ban dpass filters are used to emulate environment sounds. to avoid pcm sample saturation, the digital volume control has up to 18db of attenuation before the equalizer. a 0~+18db digital gain after the equalizer is used to correct pcm output to a suitable level. 7.10.2. pseudo stereo and spatial 3d sound there are two spatial effects in post-processing; the ps eudo-stereo effect + spatial effect, and the stereo expansion effect. the pseudo-stereo effect + spatial effect convert s a mono signal to a stereo signal by changing the phase and amplitude of the original signal followed by enhancing the spatial effect. the stereo expansion effect enhances the spatial effect when the input signal is stereo. www.datasheet.co.kr datasheet pdf - http://www..net/
