This means that bit depth conversions are happening every time you process the Audio in any way like Freezing tracks , Bouncing in place and Consolidating regions. DAWs are not going to add Dither automatically, which means that bits are being truncated every time processes are happening inside your chosen software. You can prevent any conversion or need to Dither entirely by always working in bit floating.
As a way to sum things up, here are some guidelines. Even though when working at 24 bits the audible artifacts of quantization errors are negligible, by working in 32 bit floating we can eliminate the need to add Dither during mixing and leave the one-time decision to be done in mastering.
For professional sound quality, record and render audio at a rate of at least This way, any further processing such as mixing and editing will not result in any degradation. DAWs like Ableton Live and digital audio signal processors usually work at this resolution. Here is the rendering window, as you can see there is a PCM section where you can choose to Encode or not, the Type of file WAV or AIFF , the Bit Depth mentioned previously in detail , and the Dither Options , where you can select which Dithering Mode will be used when you are rendering to any bit depth lower than bit preserving a large dynamic range.
You can choose from: No dither , Rectangular even but with more quantization error , Triangular set by default by Ableton and the safest mode to choose , POW-r 1 special for quiet recordings, like acoustic guitars, ambient or vocals , POW-r 2 for even audio clips , and POW-r 3 great for loud mixes like EDM, hard rock, or any strongly limited genre.

Anyways it's good to know everything you need about Audio Rendering so here is another chart with more information about file sizes in different types of Qualities. For you to have in mind before choosing your audio file type to store your music or Export music. Cart 0. Bit Depth In digital audio, a value describes the resolution of the sound data that is captured and stored in an audio file.
Any Audio clip with higher bit depth will have a more detailed sound recording quality. Bit Rate vs. Bit Depth They may sound similar, but they are certainly not. Bit Depth and Sound Quality For bit depth, the unit of measure is binary digits commonly known by the term bits. How does it work? Why should we use Dither? When should we use Dither? Dither is not necessary when using resolutions that are high enough.
If for some reason you need to down-sample, be sure to use Dither during the conversion. Save Dithering for when your files are headed outside of your DAW.
Dither only once when you need to render export your audio for external uses. Your music usually masks it, but with bit audio, you can sometimes hear quantization error on quiet passages, or when the music is fading in or out.
The solution is to add dither when you save the file to a lower sampling rate. When dither is added to audio with quantization distortion, it masks it a process known as "decorrelation" , making it more random and therefore harder for your ears to discern.
Instead of sounding harsh and grating, it turns the quantization distortion into a steady, low-level, analog-like hiss. Because limiters are typically the last stage in the mastering chain before dithering, most mastering-quality limiters have built-in utilities for adding dither. It lets you add dither for a variety of bit-depth targets. You can choose from two different dither types. Type 1 is designed to remove any quantization distortion from your audio. Waves recommends it for bit and bit processing.
So, the choice between Type 1 and Type 2 comes down to whether you want to completely eliminate distortion or get rid of most of it while adding less noise. IDR also lets you choose between three different noise-shaping options for modifying either type of dither: Moderate, Normal and Ultra.
Waves recommends Normal for most situations and Ultra only for the final stage of mastering a file. You can audition the different dither and noise-shaping types by listening to their effect during a quiet section of your file, such as a fade-out or a stop where the reverb tail is ringing out alone.
Use Type 2 with Ultra to add the least amount of noise to files bit and greater. If your audio does have such a section, choose Type 2. To get the maximum resolution, choose Type 1 with Ultra. When to add dither is a subject of some confusion and even controversy.
The simplest way to look at it is that you should always dither when going down in bit-depth. Bit-rate measures transmission speed for streaming.
The files your computer creates when you record are digital representations of the analog signals created by whatever you plug into your audio interface. Before you start recording, you have to choose a sample rate and bit-depth for your DAW session. Each additional bit increases the resolution that your ADC analog-to-digital converter has to measure the level of an incoming signal.
Once your files are in your DAW, lowering the resolution is tricky. Your DAW makes the calculations that power your faders, busses, and plugins at a higher resolution than your audio files. Error in your digital files has real world consequences for how your tracks sound. It can translate to harsh noise and distortion. When we reduced the resolution, we had to throw out a lot of the information in the file that allowed us to see the detail.
How that information gets thrown out is why dithering is important. Keeping the errors to a minimum has a big impact. Imagine we have to change bit files into bit ones. To make them fit, all the information from the original bit files has to go into the bit spaces. The first option is to simply cut the numbers off to make them fit.
