How to Convert DSD to PCM audio files

DSD music files have very high sound quality, but they don't work on many devices. You need to change them to other formats, such as WAV, FLAC, mp3, or m4a. These are called PCM formats. Here is how you can convert DSD to PCM files that on Mac or Windows in top-level sound quality:

  1. Open AuI ConverteR 48x44 application.

  2. Click on the Open files button and choose the DSD files you want to change. They have the extensions .dsf, .dff, or .iso (SACD ISO).
  3. On the right side of the window, in the Format section, pick the PCM format you want to change to: FLAC, WAV, ALAC, mp3, or another one. You should also choose the sampling rate and bit depth. These affect the sound quality and file size.
  4. On the bottom left of the window, click on the "..." button next to the Directory output files box. This lets you choose where to save the changed files. You can also change the file names. See here for more details.
  5. Click on the Start button.
  6. Wait for the software to finish changing the files. You can find them in the folder you chose.

How to Make Your Music Sound Better

When you listen to music, you want it to sound clear and crisp. But sometimes, the music files have noise and distortion that make them sound bad. These are the things that affect the sound quality.

When you change the format of your music files, some software may make them sound worse. This is called distortion. Different software have different amounts of distortion.

The input signal is a simple sound wave. In the picture, we can see how different software change the sound wave when they convert it.

In the lower part of the picture ("a converter software"), we can see that the sound wave is repeated and flipped. This is bad. It means that the software added extra sounds that were not in the original. These are called distortions or aliases. They make the music sound worse.

In the upper part of the picture ("AuI ConverteR"), we can see that the sound wave is the same as the original. This is good. It means that the software did not add any extra sounds. It kept the music sound as it was.

DSD to PCM conversion is a way of changing the format of the music files. Some formats are better for some devices than others. DSD files have very high sound quality, but they don't work on many devices. You need to change them to PCM files, such as WAV, FLAC, mp3, or m4a. These work on most devices.

But changing the format is not easy. You need to filter out some parts of the sound wave that are too high. Otherwise, they can mix up with the parts that you want to hear. This is what causes the distortions or aliases in the picture.

DSD to PCM conversion is based on downsampling. Because, the input sampling rate is higher than the output one (in instance, 2.8 MHz and 96 kHz, respectively).

Filtering out the unwanted parts of the sound wave takes time and skill. The better you do it, the better the sound quality will be. But it will also take longer.

Sometimes, you can make the sound quality better by making the sound wave smaller. This means that you cut off some parts of the sound wave that are not very important. This can reduce the distortion level.

In AuI ConverteR Settings, General tab, you can choose how to filter and cut the sound wave. There are different filter modes that you can try. For high-quality music files, we recommend to use the "Optimized" mode. This can reduce the noise level.

For professional use, you can use the "Optimized G5" mode. This can reduce filter ringing length. This is a slow mode, but we can expect better sound for guitars, pianos, drums, percussion.

DSD and PCM. Tech information

In spectral domain, DSD audio signal is very similar to PCM. Both ones contain audible signal in the lowest part of the spectrum (0 ... 20 kHz). After 20 kHz PCM has equal level noise for all frequencies. Sigma-delta modulated signal has a noise "hump" in the ultrasound part of the spectrum (upper 20 kHz).

Conversion DSF audio to PCM files (WAV, FLAC, AIFF, mp3,...) is digital filtration of DSD signal. After filtration noise "hump" is eliminated. And remains only audible content. High DSD's sample rate adjusted to "low" PCM's sample rate.

Configurations of DSD to PCM conversion

AuI ConverteR is a configurable software that lets you choose the features you need and pay only for them. A "module" is a part of AuI ConverteR's functionality that you can buy separately. You can buy new modules later to enhance your Modula-R major version (details). Each module is a license key that you get by email and enter in the software. A "major update" is a change in the first version number of the software version (for example, from 10.x to 11.x) and it is not free. However, your license is unlimited-time, which means you can use the software as long as you want without any subscription fees. (details)

IMPORTANT: The Free version of AuI ConverteR does not work with any modules. You need to buy a CORE module first, and then you can add other modules that are compatible with it (details). If you buy all the modules, you get the same features as the PROduce-RD version, which is a complete and cheaper package. You cannot exchange your Modula-R license for a PROduce-RD license.
