Recently a lot of wireless audio products emerged for example latest-generation wireless earphones, iPods, mobile phones and wireless amplifier items that promise to chop the cord. I’ll check out a few of the newest gadgets and technologies to discover how good they work as well as in which situations they perform best.
Products could be categorized into products with built-in and individuals with optional wireless capacity. Streaming audio products will frequently possess a plug-in slot for adding a radio LAN card. Latest generation iPods and mobile phones already include built-in Wireless and Bluetooth support.
Bluetooth is a reasonably low-cost solution but has some drawbacks that are frequently overlooked.
1) Limited range
Bluetooth devices typically have only a 30-feet range which limits Bluetooth to single-room applications.
2) Low data rate – audio compression
Bluetooth reliably supports data transmission rates close to 1 Mbps only which isn’t enough for uncompressed CD-quality audio. Therefore Bluetooth applies audio compression. This really is less critical though for compressed audio for example MP3 audio but excludes Bluetooth from use within high-quality audio applications.
3) Audio latency
Because of audio compression, Bluetooth will introduce an indication delay with a minimum of 10 ms that will make the audio to become slightly from sync in situation of video and real-time applications. This really is again a lesser problem for Audio players.
4) No multiple headphone support
Bluetooth doesn’t support a variety of earphones which can be an issue for those who have a bigger number of individuals who wish to pay attention to earphones from one transmitter device.
Wireless is yet another broadly used wireless protocol that’s also appropriate for audio streaming. Wireless does support uncompressed audio and can have issues transmitting to a lot of wireless receivers concurrently. Because of the fairly high power consumption it’s rarely utilized in wireless earphones though. Wireless works for streaming audio from the PC however since just about all Computers have Wireless access.
Wireless loudspeakers and wireless amplifier products for home entertainment loudspeakers typically use their very own proprietary protocol. Entry-level wireless earphones and loudspeakers typically still use FM transmission that provides inexpensive but is vulnerable to noise and audio distortion.
More complex wireless protocols derive from digital formats which eliminate audio degradation and incorporate advanced features for example error correction to handle interference from competing wireless devices.
Advanced wireless amplifier devices support uncompressed digital audio streaming to preserve the initial audio quality. A few of these protocols allow streaming for an limitless quantity of wireless amplifiers that is convenient for whole-house audio distribution.
