With little manufacturer information, most people have difficulty determining exactly what they are getting.
The difference between these two recording forms plays an important role in determining the ability of sound processors.
Analog audio uses a variable scale of information to reproduce the original sound waves from the source.
This process results in accurate recordings, but these recordings degrade between connections and generations of recordings.
The greater the number of samples, the closer the digital representation will be to the analog sound wave.
The sample rate is different than a bitrate.Bitraterefers to the overall data processed in the file per second.
Multiply the number of bits by the sample rate, then convert to bytes on a per-channel basis.
Mathematically:(bits * sample rate * channels) / 8.
This is the level of audio used for the 5.1surround soundchannels on DVD and Blu-ray movies.
24-bit 192 kHz solutions offer greater audio quality for those looking for the best audio definition.
Signal-to-Noise Ratio
Another aspect of audio components is asignal-to-noise ratio.
The higher the SNR, the better the sound quality.
The average person generally cannot distinguish this noise if the SNR is greater than 90 dB.
Since then, new advances in audio emerged with high-definition video formats such as Blu-ray.
Most AMD hardware labeled as 7.1 audio supportcan achieve these same levels.
Some products may carry theTHX logo.
This mark certifies that THX laboratories think the product meets or exceeds its minimum specifications.
A THX-certified product will not necessarily have better performance or sound quality than one that does not.
The manufacturers pay THX laboratories for the certification process.
