An audio codec is a computer program or device possessing capability of coding or decoding an audio digital data stream. In hardware, audio codec is a single device encoding analog audio into digital signals and decoding digital signals back into analog. Summing up, it comprises both ADC (analog to digital converter) and DAC (digital to analog converter) working hand in hand.
In software, an audio codec is computer program for implementation of an algorithm compressing and decompressing digital audio data in accordance with a given streaming media audio coding format or audio file. The algorithm’s objective is representing high-fidelity audio signal while retaining quality with minimum bits to reduce storage space and bandwidth of stored audio file transmission. Implementation of most codecs is done as libraries which can interface to more than one multimedia players.
MQA: A New Step in Audio Codec Devices
Recently an audio codec, named MQA, was launched which offers lossless audio quality in compressed size. MQA, is developed by Meridian Audio (Cambridgeshire-based hi-fi manufacturer). MQA, an acronym for Master Quality Authenticated, offers completely lossless audio in sizes of data small enough to be streamed by the current broadband connections. The workflow of the process is as follows
- MQA encapsulates original master recording in a smaller, new file.
- This file can further be downloaded & played on any of the audio devices viz. home stereo, smartphone, car stereo in better quality than CD quality.
- If the hardware possesses MQA-compatible decoder then it can play audio at a higher quality than that of original stereo master recording.
Technological Advancements and Increasing Penetration of Internet to Drive the Global Audio Codec Market
Rapid demand growth for tablets, smartphones & other mobile devices is expected to fuel growth of global audio codec market, as per the report by Future Market Insights (FMI). Rise in penetration of internet and technological advancements are positively impacting the adoption of audio codecs among end-users.
Logitech’s New BRIO 4K Pro Webcam Introduced with Extended Features
Logitech made an announcement of world’s first webcam featuring an ultra HD resolution and HDR, BRIO 4K Pro Webcam. This consists of an infrared sensor for supporting Windows Hello and facial recognition. The 4K Pro Webcam aka the Logitech BRIO is based on company’s flagship 4K sensor supporting resolution up to 4096 X 2160 at 30 fps and RightLight 3 along with HDR backlighting technology. This webcam comprises 5X digital zoom, autofocus and an infrared sensor equipped with it. The BRIO is capable of selecting between 65 degree, 78 degree and 90 degree FOV (field of view) options and involves two omnidirectional microphones along with an additional option of noise cancellation. The BRIO 4K will utilize Logitech’s most recent software package which involves background replacement. It also comprises an external privacy shutter allowing users to confirm visually that camera is not capturing video by other means.
Specifications for Logitech’s BRIO 4K Pro Webcam
In terms of compatibility, the BRIO 4K Pro can perform well with every modern version of Windows, Google Chrome OS (29.0.1547.70 version) and Apple’s macOS 10.10. Logitech has developed the BRIO 4K Pro Webcam to suit multiple enterprise-class applications, including Skype for Cisco and Business programs with certifications that are compatible. The webcam, weighing 2.2 oz (63 grams) and 102mm X 27mm X 27mm (4”X1”X1”) in size, can be attached to top of a monitor. The weight of the clip is 44 grams. The whole set weighs nearly 107 grams. The Logitech BRIO 4K Pro Webcam uses an USB 3.0 cable (Type-A) and indicates to a C-to-A connection instead of a direct C-to-C connection.
These technological innovations in audio codec products like the aforementioned MQA technology and Logitech’s Webcam are a path for a new start in the global market for audio codec devices. Many such products are in-line to be introduced in the market and set to reshape the market scenario of audio codec devices.
