The global audio codec market is expected to witness significant growth during the forecast period due to increasing demand of mobile and tablets. The increasing penetration of data traffic and internet and growing adoption of mobile phones, tablets at low cost are driving the growth of global audio codec market. The other factors contributing to the increased demand of audio code is escalating the usage of wearable devices in everyday life due to the changing consumer need and advancement in lifestyle. The global audio codec market is increasing due to the development of new software and up gradation of technologies such as internet of things (IoT). Increasing adoption of headset, headphone and wearable device is expected to increase the demand for the audio-codec market during the forecast period.
The increasing adoption of set–top boxes and video on demand services and increasing demand for infotainment are increasing the opportunities for the Global audio codec market. However, the restraints hampering the growth of the global codec market are continuous optimization of the component size and lack of expertise in handling the audio codec device.
An audio codec is a computer program that compresses and decompresses digital audio data according to a given audio file and streaming media audio coding format. The objective of the audio codec device is to represent high-fidelity audio signal with minimum number of bits. The important feature of the device is to retain the transmitted quality of audio. The audio codec device helps in reducing the storage space and the bandwidth required for transmission of the stored audio file.
An audio codec contains line inputs & micro phone, signal routing & mixing channels, amplifier block, multiple analog-to-digital converter (ADC) and digital-to-analog converter (DAC) channels. It also consists of variety of output drivers, including line outputs, and headphone and loudspeaker drivers as well as small digital processing block that consists of interpolating filters and standard integrated interchip sound (I2S) and digital audio interface. Most of the audio and the video formats use some sort of compression so that it does not occupy enough amount of disk space. All the audio and video files are compressed with a certain codec when they are saved and decompressed by the codec, when they are played back. Some common types of codec include MPEG and AVI for video files and WAV and AIFF for the audio files. Codec is also used to compress streaming media such as audio and video, which enables it to broadcast a live audio or video clip over a broadband internet connection.
