Sample Rate
The number of times per second an audio signal is measured is determined by the sample rate. To reproduce frequencies up to 20 kHz (the upper limit of human hearing) without loss, at least 40.000 measurements per second are necessary; therefore, 44,1 kHz has become established as the audio standard, while 48 kHz is currently the recommended value for digital music platforms.

What sample rate should I use?
The sample rate you should use depends on the purpose for which the audio signal is intended.
A sample rate of 44.1 kHz is common because it offers good sound quality without requiring too much storage space or bandwidth. It is also widely used for music streaming services, although it is not always the best balance between file size and quality. For releases on digital music platforms, we recommend 48 kHz.
The 48 kHz sample rate is often used for professional audio recording and editing and offers slightly better sound quality than 44,1 kHz. It is commonly used for films, television programs, streaming platforms and other audiovisual content intended for high-quality release.
The sample rate is an early mastering decision with long-lasting repercussions — where it comes into play, the Mastering Guide.
A 96 kHz sample rate is frequently used for very high-quality audio recording and editing, offering the highest sound quality. However, it also requires more storage space and bandwidth and may therefore not be the best choice for publishing on digital platforms.
It's important to note that the sample rate can vary depending on the genre and the music producer's preferences, and that there is no universally "correct" sample rate. It's crucial to choose the sample rate carefully to ensure the audio signal has the desired quality and is suitable for its intended purpose.
Use technology correctly within the overall mix: Sample rate, headroom and how signal structure interact throughout the entire mixing process is shown in our Mixing Guide in a clearly structured process.
What is a sample rate?
The sample rate is a measure of the number of samples taken of an audio signal per second. It is measured in Hertz (Hz) and indicates how often a sample of the audio signal is taken per second. A sample is a measure of the volume of the audio signal at a given moment.
The sample rate is an important factor for the quality of audio signals, as it directly affects the signal's bandwidth. A higher sample rate allows more details of the audio signal to be captured, thus improving the signal quality. However, a higher sample rate also requires more storage space and bandwidth to store and transmit the audio signal.
In the audio industry, different sample rates are used depending on the intended use of the audio signal. Some of the most commonly used sample rates are 44,1 kHz, 48 kHz, and 96 kHz. The 44,1 kHz sample rate is frequently used for CDs, while the 48 kHz and 96 kHz sample rates are frequently used for... professional audio recordings and editing are used. However, it is important to note that the sample rate will vary depending on the genre and preferences of the music producers may vary.

What is the difference between 44,1 and 48 kHz?
44,1 kHz is the classic standard for CDs and music streaming, while 48 kHz has become established for film, video, and broadcast. Sonically, the two are practically indistinguishable to the end listener, as both cover the entire audible frequency range. The decisive factor is the target medium – 44,1 kHz is common for music releases, while 48 kHz is more suitable for video projects. 48kHz the safe choice.
Does a higher sample rate affect sound quality?
A higher sample rate, such as 96 or 192 kHz, extends the theoretically audible frequency range beyond the limits of human hearing, but usually offers no discernible advantage in the final audio result. It is primarily useful during recording and editing, for example for pitch shifting or time stretching, but it increases file size and processing load. For most music productions, 44,1 or 48 kHz is perfectly adequate.
What does the sample rate have to do with the maximum frequency?
According to the sampling theorem, a digital recording can only correctly capture frequencies up to half the sample rate – the so-called Nyquist FrequencyAt 44,1 kHz, this limit is around 22 kHz, which is above the human hearing range. The sampling rate therefore determines how high-pitched sounds can be digitally reproduced.
