Bit depth in audio production

Bit depth is an important value in audio production Recording, mixing and Mastering.

What is bit depth in audio production?

Bit depth determines the resolution of the audio signal and influences the quality and accuracy of the recording. A higher bit depth allows for a larger dynamic Range and lower noise because finer nuances in the signal can be recorded.

At the nuclear Music production A bit depth of 24 bits is often used because it offers a wide dynamic range and enough latitude for editing and Mixing the audio tracks without loss of quality.

How are the individual bits calculated?

Bit depth determines the number of possible digital values ​​that can be used to represent a sample. The number of bits determines how fine the gradations between the possible values ​​are.


The possible values ​​are calculated by 2 to the power of n, whereby n is the number of bits. Example:

  • With a bit depth of 16 bits, there are 2 to the power of 16 = 65.536 possible values.
  • With a bit depth of 24 bits, there are 2 to the power of 24 = 16.777.216 possible values.


These values ​​represent the possible ones Amplitudes that a single sample can accept. The higher the bit depth, the finer the gradations between individual amplitudes, resulting in more precise and detailed audio reproduction.

How dynamic are 16 and 24 bits?

16-bit audio can be approx. 65.536 different volume levels while 24-bit audio is approx. 16.777.216 different volume levels enabled. That means that the Dynamic range is about 96 dB.


When the audio signal reaches or exceeds the maximum level limited by the 16-bit bit depth, distortion known as clipping can occur. Clipping occurs when the peaks of the signal are clipped, which can result in an unpleasant, distorted sound.


This variety of gradations means that 24-bit audio has a larger dynamic range has as 16-bit audio. Dynamic range is the difference between the quietest and loudest sound a system can record or play back. For 24-bit audio, this range is approximately 144 dB.

How much dynamic does 32 bit float have?

Overall, 32-bit float audio offers very high audio quality and flexibility for professional audio applications. It is commonly used in high-end recording equipment, digital mixing consoles and audio workstations.


32-bit float audio is another type of audio bit depth used in professional audio recording and processing. Unlike fixed bit depths such as 16-bit and 24-bit, 32-bit float uses a floating-point representation, similar to the use of decimal numbers in mathematics.


32-bit float offers an extremely large Dynamic range of approx. 1530 dB, which even exceeds the dynamic range of 24-bit audio. This enables very precise recording and Processing audio signals without signal distortion.


Another advantage of 32-bit float is that it can handle clipping better. Even if the input signal exceeds the maximum level, the 32-bit float format can better handle these clippings and still deliver accurate recordings.

What is the maximum level in terms of bit depth?

Maximum level refers to the highest level or amplitude of an audio signal that can be processed by a recording device or other audio device without clipping or distortion.


In audio technology it is important that the input signal Maximum level does not exceed, as this can cause unwanted distortion that affects audio quality. Gain staging is extremely important for this.
