A Look At Some Of The Trendiest Wireless Audio Gizmos
Latest wireless audio gadgets such as iPods, wireless headphones and cell phones support newest wireless protocols. These protocols are supposed to eliminate the cord and provide perfect high-fidelity audio. We will check out some of the latest devices to learn which applications they work for.
Products can be categorized into devices with built-in and those with optional wireless functionality. Streaming audio devices will frequently have a plug-in slot for adding a wireless LAN card. Latest generation iPods and cell phones already come with built-in WiFi and Bluetooth support.
Bluetooth is fairly widespread as a low-cost wireless option. Still, Bluetooth does have some drawbacks. These weaknesses are often ignored but will have an impact on high-quality audio applications.
1) Short range
The range of Bluetooth devices is generally only 30 ft. This excludes Bluetooth from multi-room applications.
2) Small data rate – audio compression
Bluetooth will utilize audio compression since it does not reliably offer a high-enough data rate for uncompressed audio. This is less critical however for compressed audio such as MP3 audio but excludes Bluetooth from use in high-quality audio applications.
3) Signal latency
Because of audio compression, Bluetooth will introduce a signal delay of no less than 10 ms which will cause the audio to be to some extent out of sync in case of video and real-time applications. This is yet again less of a problem for MP3 players.
4) Lacking multi-headphone support
Bluetooth does not support any quantity of headphones which may be a problem if you have a larger number of people who want to listen to headphones from a single transmitter device.
Uncompressed audio streaming is supported by WiFi. WiFi is a very widespread protocol. Yet, WiFi also has drawbacks in regard to simultaneous transmission to a number of receivers. It is convenient for streaming music from a PC because of the high availability but is usually not utilized in wireless headphone products because of the fairly high power consumption of WiFi.
While newest-generation wireless speakers and wireless amplifier products employ proprietary digital technologies, low-cost products regularly still depend on FM transmission which is noisy and has high audio distortion and high susceptibility to radio interference.
More recent wireless audio protocols are based on digital transmission. This avoids audio degradation. Some protocols also incorporate error correction to cope with interference from other wireless products.
Newest-generation wireless amplifiers permit streaming to an infinite number of receivers and support uncompressed audio transmission.
Some of these protocols support low-latency audio transmission which assures that the audio of all speakers will be in sync in a multi-channel application. Normally newer generation wireless audio transmitters will operate at 2.4 GHz. Some transmitter products, such as Amphony’s line of devices, work at the less crowded 5.8 GHz frequency band.
These wireless amplifiers also differ regarding amplifier output power, standby power consumption and audio quality. A high-quality audio amplifier is fundamental for optimum sound quality. Digital Class-D amplifiers offer high power efficiency of no less than 80%. They also have low standby power, normally less than 5 Watts. This minimizes heat and keeps them cool during operation. Some digital amplifiers, on the other hand, have fairly high harmonic distortion. It is essential to choose a wireless amplifier with low audio distortion. This will make sure good sound quality. High-quality amplifiers have audio distortion of 0.05% or less.
