We use an Audio Processor to help in audio processing, also known as audio signal processing. Audio processing is used to enhance and clean up audio signals before they are transmitted. There are two forms of audio processing.
Analog converts a sound wave into an electrical signal. The signal looks like a sound wave and is processed with least...
processing Digital audio processing converts an audio signal into digital form. This is normally a binary code which can be interpreted by computer. Digital alters the sound from a continuous wave to other information meaning the ear hears no difference in the sound.A simple definition is, an audio processor is a device that controls and changes an audio signal improving the sound.

Audio Processors are available in different package types.
LFCSP – Lead Frame Chip Scale package LQFP – Low profile Quad Flat pack package SOIC – Small outline integrated circuit TQFP – Thin quad flat pack TSSOP - Thin shrink small outline packageAudio processors are available with a various Pins, sizes, channels, audio formats and voltages.
What is an Audio switch?An audio switch is a semiconductor accessory part used in the switch configuration for 3-pole to 4-pole accessories typical found in things like mobile phones/mp3 devices.How do they work?They work by helping creating a link between universal audio devices that may not typically be used together. For example being able to connect your mobile phone to a different brand of headphones that normally may not be compatible (its worth checking first what is compatible as not all devices can connect to an audio switch)....
.Audio switches also have a great feature called Moisture detection. Many devices now are portable and therefore face the issue of moisture being introduced to the device. This can then trick the device into thinking it has an accessory attached. This moisture detection feature helps the device recognise false and improper attachments via moisture.Features and benefits: Accessory plug-in detection available Moisture detection Operating temperatures range from -40°C to 85°C Send/End key pressed detection MIC Switch typeWhere might I use one? Mobile phone handsets MP3 players Portable peripheral devices 3.5 to 2.5mm audio jacks
