Furthermore, the noise is randomized (uncorrelated) to mask any errors that can arise when reducing the bit depth of a signal.<\/p>\n\n\n\n<p>The process of dithering audio masks unwanted noise and artifacts that quantization distortion causes. As with dithering digital images, dithering in audio helps restore the fidelity of digital audio files.<\/p>\n\n\n\n<a name=\"difference-quantization\"><\/a>\n\n\n\n<p>Our goal with audio dithering is to make mask quantization distortion and make it less perceivable to listeners by randomizing higher-order harmonics in the digital signal. <\/p>\n\n\n\n<h4><strong>The difference between quantization, quantization noise, and quantization distortion <\/strong><\/h4>\n\n\n\n<p>Before we go any further, let&#8217;s clear up any risk of confusion. Let&#8217;s understand the differences between quantization, quantization noise, and quantization distortion.<\/p>\n\n\n\n<h5><strong>Quantization <\/strong><\/h5>\n\n\n\n<p>Quantization is another word for analog-to-digital conversion (ADC). So, quantization is the process of converting an analog signal to digital via an A-to-D converter. <\/p>\n\n\n\n<p>With a determined bit depth, you can sample an analog signal and store those samples as digital bits. And we need enough bits to store all of our audio samples if we want to recreate our signal accurately.   <\/p>\n\n\n\n<p>So, the higher your bit depth the more audio resolution your project will have.<\/p>\n\n\n\n<h5><strong>Quantization noise<\/strong><\/h5>\n\n\n\n<p>Next, quantization noise is the difference in the level of noise between a digitally quantized signal and its analog original. It&#8217;s the amount of noise that the A2D conversion generates<\/p>\n\n\n\n<p>Quantization noise is generated when there is a problem rounding a particular sample to its closest bit. However, it&#8217;s less likely to occur at higher bit depths.<\/p>\n\n\n\n<h5><strong>Quantization distortion<\/strong><\/h5>\n\n\n\n<p>Finally, quantization distortion &#8211; our focus for this article &#8211; occurs when a sample is stored in a digital bit that doesn&#8217;t represent its amplitude.<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large is-resized\"><img loading=\"lazy\" src=\"https:\/\/routenote.com\/blog\/wp-content\/uploads\/2022\/10\/Ideal-ADC-vs-Quantisation-RouteNote-Blog.jpg\" alt=\"\" class=\"wp-image-93502 lazyload\" width=\"413\" height=\"380\"\/><\/figure><\/div>\n\n\n\n<p>Quantization distortion occurs at lower bit depths because there aren&#8217;t enough available bits to store every sample of our analog signal correctly. Therefore, quantization distortion is a problem you&#8217;ll run into if you reduce the bit depth of your digital audio file (known as <strong>downsampling<\/strong>).<\/p>\n\n\n\n<p>Having enough digital bits removes the risk of any amplitude samples being too high or low from the next available digital bit. <\/p>\n\n\n\n<a name=\"harmonics\"><\/a>\n\n\n\n<p>So measuring a continuous analog wave with a finite number of bits leads to problems. And the resulting distortion noise occupies high harmonic intervals when it does. It&#8217;s especially noticeable in quieter parts of a track like in reverb tails in reverb tails, rests, and fade-outs.  <\/p>\n\n\n\n<h4><strong>Higher harmonics vs lower harmonics<\/strong><\/h4>\n\n\n\n<p>The particular harmonics that a distortion generates are what make it a pleasant or unpalatable distortion. <\/p>\n\n\n\n<p>Distortions occupying higher harmonic intervals are typically less enjoyable than those of lower harmonics. This is because distinguishing between a fundamental frequency and lower harmonics is harder than it is identifying higher harmonics. <\/p>\n\n\n\n<p>In contrast, it&#8217;s easy to discern between higher harmonics and a fundamental frequency. As a result, distortions with higher harmonics are unlikeable.       <\/p>\n\n\n\n<p>Examples of low-order harmonic distortions that we use creatively include tape and tube-based distortions.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Mixing And Mastering A Song - 5 Top Tips\" width=\"720\" height=\"405\" src=\"https:\/\/www.youtube.com\/embed\/7l-AH41hybU?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<a name=\"What-does-dithering-do\"><\/a>\n\n\n\n<hr class=\"wp-block-separator\"\/>\n\n\n\n<h3><strong>What does dithering do?<\/strong><\/h3>\n\n\n\n<p>Dithering replaces and randomizes the unpalatable harmonics with noise, thereby masking any rounding error. As a result, those higher harmonics are no longer directly related to the fundamental frequency. This masks our perception of them and increases the resolution of our audio.<\/p>\n\n\n\n<p>Therefore, dithering audio creates randomized noise which is harder to hear than the correlated noise of quantization distortion.<\/p>\n\n\n\n<p>Not only have we made it more difficult to hear the quantization distortion, but we have decreased the strength of the distortion so much so that the&nbsp;noise floor&nbsp;drops to the bottom of the dynamic range of our signal.<\/p>\n\n\n\n<a name=\"why-reduce-bit-depth\"><\/a>\n\n\n\n<p>In summary, when dithering audio we&#8217;re replacing the higher harmonics that quantization distortion generates for randomized noise.<\/p>\n\n\n\n<h4><strong>Why would you reduce bit depth?<\/strong><\/h4>\n\n\n\n<p>Depending on the <span style=\"text-decoration: underline\" class=\"underline\"><strong><a href=\"https:\/\/routenote.com\/blog\/build-a-music-production-pc\/\" target=\"_blank\" rel=\"noreferrer noopener\">capabilities of your computer<\/a><\/strong><\/span>, you could record music at a bit depth of 32-bit.

Some don&#8217;t accept tracks with a bit depth higher than 16-bit (Spotify) while others accept 24-bit audio (Apple Music, Amazon Music).<\/p>\n\n\n\n<p>Consequently, you will have to reduce the bit depth of the project during the mastering stage.<\/p>\n\n\n\n<div align=\"center\">\n<figure class=\"wp-block-embed is-type-wp-embed is-provider-routenote-blog wp-block-embed-routenote-blog\"><div class=\"wp-block-embed__wrapper\">\n<blockquote class=\"wp-embedded-content\" data-secret=\"m2Gi3FVXN6\"><a href=\"https:\/\/routenote.com\/blog\/what-is-bit-depth\/\">Bit depth: what it is and how it impacts audio quality<\/a><\/blockquote><iframe class=\"wp-embedded-content\" sandbox=\"allow-scripts\" security=\"restricted\" style=\"position: absolute; clip: rect(1px, 1px, 1px, 1px);\" title=\"&#8220;Bit depth: what it is and how it impacts audio quality&#8221; &#8212; RouteNote Blog\" src=\"https:\/\/routenote.com\/blog\/what-is-bit-depth\/embed\/#?secret=m2Gi3FVXN6\" data-secret=\"m2Gi3FVXN6\" width=\"600\" height=\"338\" frameborder=\"0\" marginwidth=\"0\" marginheight=\"0\" scrolling=\"no\"><\/iframe>\n<\/div><\/figure>\n<\/div>\n\n\n\n<a name=\"When-to-dither\"><\/a>\n\n\n\n<hr class=\"wp-block-separator\"\/>\n\n\n\n<h3><strong><\/strong><strong>When you should dither<\/strong> <strong>your audio<\/strong><\/h3>\n\n\n\n<p>A lot of mastered tracks are reduced to 16-bit down from 32-bit or 24-bit in line with the specifications of streaming services &amp; online stores.

In other words, no EQ shapes the frequency response of the noise.<\/p>\n\n\n\n<h5><strong>Type 2 POW-r<\/strong><\/h5>\n\n\n\n<p>Secondly, type 2 POW-r&nbsp;dithering&nbsp;is suited to speech and dialogue-focused audio. <\/p>\n\n\n\n<p>Unlike type1, Type 2 POW-r utilizes an EQ curve that shapes the noise and attenuates&nbsp;the&nbsp;noise&nbsp;level at&nbsp;the 2kHz mark. Additionally, Type 2 POW-r increases the level of noise at amplifies&nbsp;at&nbsp;14kHz&nbsp;and&nbsp;above too.<\/p>\n\n\n\n<h5><strong>But what is noise shaping?<\/strong><\/h5>\n\n\n\n<p>In a nutshell, noise shaping&nbsp;is the process of attenuating or increasing the level of a specific frequency band in the noise via an EQ. <\/p>\n\n\n\n<p>Noise shaping allows us to be flexible while dithering our audio as we can apply more or less noise where necessary in the frequency spectrum.<\/p>\n\n\n\n<p>The noise shaping in Type 2 POW-r dithering increases and attenuates the level of noise where the human voice is more prevalent or absent respectively. <\/p>\n\n\n\n<p>As a result, the noise&nbsp;it introduces masks any quantization distortion effectively without becoming noticeable<\/p>\n\n\n\n<h5><strong>Type 3 POW-r<\/strong><\/h5>\n\n\n\n<p>Finally, Type 3 POW-r dithering&nbsp;is for&nbsp;audio with a lot of dynamic range and less compression.<\/p>\n\n\n\n<p>Type 3 also utilizes an EQ curve, but the frequencies that are attenuated &amp; amplified are greater than in Type 2 POW-r dithering.<\/p>\n\n\n\n<div align=\"center\">\n<figure class=\"wp-block-embed is-type-wp-embed is-provider-routenote-blog wp-block-embed-routenote-blog\"><div class=\"wp-block-embed__wrapper\">\n<blockquote class=\"wp-embedded-content\" data-secret=\"aBQREw35XC\"><a href=\"https:\/\/routenote.com\/blog\/reduce-background-noise-while-recording\/\">7 ways to reduce background noise while recording<\/a><\/blockquote><iframe class=\"wp-embedded-content\" sandbox=\"allow-scripts\" security=\"restricted\" style=\"position: absolute; clip: rect(1px, 1px, 1px, 1px);\" title=\"&#8220;7 ways to reduce background noise while recording&#8221; &#8212; RouteNote Blog\" src=\"https:\/\/routenote.com\/blog\/reduce-background-noise-while-recording\/embed\/#?secret=aBQREw35XC\" data-secret=\"aBQREw35XC\" width=\"600\" height=\"338\" frameborder=\"0\" marginwidth=\"0\" marginheight=\"0\" scrolling=\"no\"><\/iframe>\n<\/div><\/figure>\n<\/div>\n\n\n\n<a name=\"dither-audio-yourself\"><\/a>\n\n\n\n<hr class=\"wp-block-separator\"\/>\n\n\n\n<h3><strong>Final thoughts: should you dither audio yourself? <\/strong><\/h3>\n\n\n\n<p>Dithering is a necessary practice only when mastering. <\/p>\n\n\n\n<p>More specifically, only apply audio dithering if you need to reduce the bit depth of your project before <span style=\"text-decoration: underline\" class=\"underline\"><strong><a href=\"https:\/\/routenote.com\/blog\/what-is-bounce-in-music-production\/\" target=\"_blank\" rel=\"noreferrer noopener\">exporting from your DAW<\/a><\/strong><\/span>.
