How is digital audio quality measured?
Measured in decibels, SN ratio is the ratio of quality audio to noise (fidelity of the sound equipment). SN ratio is measured for many devices including CD/DVD players, receivers, etc. Devices with high SN ratio – 90 to 100 decibels – are viewed as having high fidelity to the sound source.
How is digital audio recorded?
Digital sound recording, method of preserving sound in which audio signals are transformed into a series of pulses that correspond to patterns of binary digits (i.e., 0’s and 1’s) and are recorded as such on the surface of a magnetic tape or optical disc.
How do I record high quality audio?
Over on Android, Titanium Recorder (Android only, free with ads) provides one of the most complete solutions for sound capture. Tap the menu button (three dots) on the top right and go to Settings.

What audio quality depends on?
The sound quality of a reproduction or recording depends on a number of factors, including the equipment used to make it, processing and mastering done to the recording, the equipment used to reproduce it, as well as the listening environment used to reproduce it.
Is 320Kbps good sound quality?
For most general listening 320kbps is ideal. Of course, CD-quality audio that stretches to 1,411kbps will sound better. To determine the best audio bitrate you need to also assess your needs. If storage space is a concern high bitrate files will rapidly eat into your available space.
What is a good bitrate for 1080p?
Recommended video bitrates for HDR uploads

Is 128 kbps sound good?
The absolute lowest MP3 bit rate you should consider is 128kbps. This was often referred to as being CD quality, but it’s far from being so. This bit rate will allow you to get much more music on to your MP3 player but you’ll sacrifice a great deal of audio quality as a result.
