Ten Of The Best: Audio Interfaces Audio interfaces (sometimes still referred to as ‘sound cards’, a relic of the days when most interfaces took the form of internal expansion cards) are the devices that convert analogue audio signals to digital on the way into your computer, then convert the digital signals back into analogue on the way out.

Audio power Audio power is the electrical power transferred from an audio amplifier to a loudspeaker, measured in watts. The electrical power delivered to the loudspeaker, together with its efficiency, determines the sound power generated. Amplifiers are limited in the electrical energy they can output, while loudspeakers are limited in the electrical energy they can convert to sound energy without being damaged or distorting the audio signal. These limits, or power ratings, are important to consumers findi

Broadband: Understanding Wireless Channels Wi-Fi Channels: Every Wi-Fi network transmits and receives data on a certain frequency, or channel. As Wi-Fi data is digital, many different devices can communicate successfully on the same channel. By default the channels used are typically either channel 6 or channel 11.

Audio Spectrum Explained The audio spectrum is the audible frequency range at which humans can hear. The range spans from 20 Hz to 20,000 Hz and can be effectively broken down into seven different frequency bands, with each having a different impact on the total sound.idrange: 500 Hz to 2 kHz. The midrange determines how prominent an instrument is in the mix. Boosting around 1000 Hz can give instruments a horn like quality. Excess output at this range can sound tinny and may cause ear fatigue.

what does audio channel really mean? Re: what does audio channel really mean? A channel is something through which data(in the form of electro magnetic data or electric current or other wave) signal travels from source to destination. Physically a audio channel can be said as a simple wire through which electrical signal is propagated. This signal is analog in nature and contain many frequencies. In the case of sterio audio we have two channels. A sterio audio is recorded by using two different micro phones. So we have to set of data.

What is an audio file format and which should I use? An audio file format is a file format for storing audio. There are various audio file formats and they all encode audio data in different ways. There are two different approaches; compressed or non-compressed formats. Other differences between formats include licenses. Let take a closer look at these differences and which formats suit which purposes best.
