Dither only as the very last step when rendering to CD, don't dither at any point beforehand. CD render is not destructive. Originally Posted by tweeksound. Thanks for the quick replies schwa and darjama! Isn't Type 3 the best? Is there a way to chose? Is that what JS uses?
I used to use Auditions advanced dither options and found the best sounding combo. Any noise shaping algorithm is solving the problem "how can I best filter this truncation noise into less audible frequencies within this bit depth context. Last edited by schwa; at AM. Very cool. I guess I may do a blind comaprison at some point but like I said, I havn't heard anything bad from the psycho. Remember that pow-r is quite old now. It goes in the Master channel of everything I do.
Last in line, Master Fader at 0db. What you hear is what you get. Middleman 3 is definitely better because it's the biggest number. I think 1. I've used it ever since. It may not be any better, but having done the "test", I am able to sleep at night without wondering - it's another thing off my checklist!
POW-r 3 is supposed to be the most transparent of all, at least according to the Sonar Help files. Song must sound really great if dither settings are the most important thing to tweak But POW-r 3 won't let you down.
I never could hear a difference between any of the dithering options in Sonar. I did hear a difference though when I tried out Ozone's dithering. At first I thought I was using it wrong and there was no dithering being applied at all and I was listening to my original master. Maybe it was in my head because I was tinkering with a new gadget. You know how that can be.
You mean the "Placebonic Effect"? You need to use randomized double-blind sampling and no, that has nothing to do with the I have to laugh! None of you can hear ANY difference between any of the algorithms, or in fact dithered vs not at all I would bet!
I'm deaf on that one. Now that I have listened, I have my choice and I'm done. Learn to lie to yourself, you will be much happier in the long run Well put, Sijel!
In light of all this, you might be amused to read Apogee's sales pitch for their proprietary dither algorithm, UV And we all know Apogee is never prone to hyperbole! I'm sorry Pow-r noise-shaped dither. Disadvantages: less noise shaping than Pow-r types 2 and 3, not recommended for operations where dither will be applied successively e.
Advantages: lowest perceived loudness, highest quality settings, recommended for audio export. Disadvantages: highest CPU-intensive settings, not recommended for operations where dither will be applied successively e.
Pow-r same as Pow-r 2 except most CPU-intensive and transparent of all choices. Rectangular--essentially white noise, no noise shaping. Advantages: least CPU-intensive, lowest signal-to-noise ratio, preferable to shaped dither when successive dithering can occur e.
Disadvantages: suffers from intermodulation distortion, higher perceived loudness than Pow-r dither. Triangular--higher level than rectangular, no noise shaping. Advantages: low CPU-intensive dither, superior to Rectangular as it does not suffer from modulation noise effects. Preferable to shaped Pow-r dither when successive dithering can occur e.
I then performed a null test between the bit audio file, and each subsequent file, in an attempt to measure the noise generated from each form of dithering, and from the 1 instance of truncation.
This is the method used for this test. Here are the results from each null test, measured using a True Peak Meter. The entire idea behind dithering is to reduce the amount of distortion that occurs, in the hopes of increasing the nuanced details of a recording. Perhaps in this example here, the original electrical noise inherent to the recording served as a means of dithering, rending additional dithering unnecessary, but this cannot be stated with complete certainty.
With all this in mind, the need to dither is questionable, however, further testing on the topic is needed before reaching a conclusion. That being said, as high fidelity recordings become compatible with more streaming services, then the need for dithering will become non-existent.
This seems to the case for the not-so-distant future, as quicker streaming, larger hard-drives, and a desire for the highest fidelity possible are driving listeners to better-sounding music.
In the mean-time keep your dither plugins simply for the sake of having them. Dithering is used to cover the effects of quantization distortion. By using noise, any harmonics generated during bit depth degradation will be randomized and in turn less perceivable.
Dithering is typically applied right before exporting a project. That being said, it is best to save dithering for the mastering process to avoid excessive noise generation. Although the intention behind dithering makes sense, when put into practice it may not always be necessary. This is particularly true when bouncing a higher bit depth audio file, down to a still relatively high bit depth audio file — as is the case for a bit to bit conversion.
Regardless, as 24 bit becomes the standard for download and streaming, there will no longer be a need for dithering. What is Dithering? Pleasant harmonic generation is created from tape, tube and transistor saturation.
Above is a visual representation of bit depth distortion on a Hz sine wave as the fundamental. Notice that the harmonics are primarily occupying the higher frequency range. Above is a visual representation of 3-bit quantization.
