Dynamic range is the difference between the lowest and highest volume of a signal that can be recorded. Bit Depthīit Depth is the number of “bits” captured in each sample per second.Īs bit depth changes, so does the dynamic range. There is debate in the audio community about the value (or lack of) of using higher sample rates for situations that don't fall into the above categories (I.e., for general recording purposes). Since sample rates of 44.1/48kHz allow us to capture frequencies spanning the full range of human hearing, you wonder what the purpose of higher sample rate options is. What's the point of higher Sample Rate options? The range of human hearing is from around 20Hz to 20kHz (though we lose the ability to hear the higher frequencies as we get older) so sample rates of 44.1 & 48kHz are more than capable of capturing the full range of the human audible spectrum.Īs such, the vast majority of digital music available by typical distribution methods (streaming on Spotify/Apple Music, CDs) is at a 44.1kHz sample rate, audio for film tends to be at 48kHz 3. This means, when using a sample rate of 48kHz, we can capture audio frequencies up to 24kHz. Sample rate ÷ 2 = maximum frequency that can be correctly captured The maximum frequency that can be captured correctly by a recording device 1 is limited by the sample rate the device is set to. 48000 (forty-eight thousand) samples are being captured each second by your audio recording device.Īs you increase the sample rate, you capture more samples of the incoming audio signal each second.

Sample Rates come in 'bands' and common examples include:įor example, when recording using a sample rate of 48kHz. Sample Rate values are typically written in kHz (kiloHertz). It is to audio what frame-rate (Frames Per Second) is to video. Sample Rate is the number of times the audio is captured per second.
