Aug 13, 2024 · You can then take these figures and find the theoretical maximum bitrate — the higher the bit depth and/or sample rate of the file, the greater the bitrate. For example, a CD uses a 16-bit signal that’s sampled at 44.1 thousand times per second (kHz). The bitrate for such a file would be 1,411kbps if it wasn’t compressed in any way.

In order to record sound digitally, your analogue to digital convertor captures thousands of samples of the analogue signal every second. Each sample is assigned a value which is used to represent the amplitude of that sample. Bit depth defines the number of values that are available in each sample. As a result, bit depth defines the dynamic range ...
When your analogue signal is sampled, its amplitude is matched to the closest of the available digital values. This process is called quantization. However, no matter how many values are available, the amplitude of the analogue signal will not always correspond perfectly with an available value. Sometimes the amplitude of the signal will fall betwe...
The most common bit depths for recording and bouncing audio are 16 bit and 24 bit. 16 bit provides each sample with 65,536 possible amplitude values. 24 bit provides each sample with 16,777,216 possible amplitude values. As such, 16 bit provides you with 96dB of dynamic range between the noise floor and 0dBFS. 24 bit provides you with 144dB of dyna...
There is something of a misconception that higher bit depths result in better quality audio or higher fidelity sound. A question that people ask is “does 24 bit sound better than 16 bit”? This confusion likely originates from the fact that a higher bit depth is referred to as having a higher ‘resolution’. This makes people think of the resolution o...
When it comes to recording, even at 16 bit, the noise floor is very low. So you could record at 16 bit and still have a decent amount of dynamic range. A more common practice however, and something of a standard, is to record at 24 bit. Simply because recording at 24 bit gives you more dynamic range to work with. It offers you the ability to record...
So, what bit depth should you use for the final bounce of your song? That’s the audio file that you will upload to a distributor to release on iTunes, Spotify etc. Well, the standard bit depth for this for a long time was 16 bit. That was because to burn an audio file to an audio CD, the file has to be 16 bit. But many online platforms now allow yo...
With the basics covered, let’s move onto 32 bit floating point. You’ve probably seen this as one of the options alongside 16 bit and 24 bit when you create a new session or bounce audio. First, it’s important to know that bit depths come in 2 different forms. The first is ‘fixed point’, also known as ‘integer’. The second is ‘floating point’. So fa...
So, is it better to work with 32 bit floating point files rather than 16 or 24 bit? Well, you can create 32 bit float files from the outset if you want. You do this by setting the bit depth of your session to 32 bit float before you record. That way, you will capture your audio at the fixed point bit depth that your interface is capable of, but it ...
You also have the ability to bounce down audio as a 32 bit floating point file. As I mentioned earlier, this should only be used if the audio file is going to be imported into a DAW. It’s not suitable for the final bounce that you will upload to a digital distributor. Bouncing 32 bit float files gives you an advantage that a fixed point bit depth f...
Something about 32 bit floating point that’s worth considering is this… Although you have the ability with 32 bit floating point processing to let your audio go past 0dBFS in your DAW without clipping, I still recommend that you treat 0dBFS as a ceiling. This is for two reasons. Firstly, you may have older third party plugins that you use which don...
- Sample Rate And Bit Depth Explained. What Are Samples? Before we learn about sample rates and bit depth, we need to know what ‘samples’ are in this context.
- What Bit Depth Should I Use? There are three different scenarios where this question applies: recording, mixing, and rendering. As I’ve already stated, you should record in 24 bit quality, as 16 bits is too low.
- What Sample Rate Should I Use? (44.1 kHz vs 48 kHz) I would argue that all producers should work at 48 kHz. But it’s also ok if you don’t. Music comes first, and even at 44.1 kHz, you’ll still have excellent sound quality.
- Myth-busting. On that note, there are a few myths I see repeated in the course of this debate that I want to deal with right here and now because I am sick to death of them.

Oct 20, 2023 · A bit depth of 16-bit for a sample rate of 44.1kHz is enough to reproduce the audible frequency and dynamic range for the average person, which is why it became the standard CD format. Should You Always Record in 192kHz/24-bit?
Mar 20, 2023 · The promise is simple—superior listening quality thanks to more data, aka bit depth. That’s 24 bits of digital ones and zeroes versus the puny 16-bit hangover from the CD era. Of course, you’ll have to pay extra for these higher quality products and services, but more bits are surely better right?
Apr 23, 2023 · 16-bit is the standard bit depth for audio CDs, which have a sample rate of 44.1 kHz. This means that 44,100 samples are taken per second, and each sample is represented by 16 bits. This results in a data rate of approximately 1.4 megabits per second (Mbps) for CD-quality audio .
