Notes on DST SACD-ISO Not Supported for New X5/New X3

recently, we received some feedback that the new X5/new X3 official instructions support SACD-ISO, but many people do not support the actual test tips after downloading SACD-ISO album. here I

, please explain.

First of all, let's explain the types of SACD-ISO resources:

SACD and DSD will not be explained here. There are many on the Internet. I believe everyone who has installed the system will not be unfamiliar with ISO. This is a mirror file. For DSD

said that the following three different DSD formats can be extracted through software extraction, namely DSF/DFF(DSDIFF)/DST, of which DSF is Sony standard format and DFF is more

Philips's name, both formats are uncompressed. DST is a lossless compression form of DSD and is an abbreviation of Direct Stream Transfer, just like PCM's

FLAC, WAV, and APE, DST can compress and store DSD source files, and maintain the integrity of all DSD source files after decompression.

For example, DFF/DSF corresponds to WAV, which is equivalent to only one lock. DST corresponds to FLAC and APE, and requires two locks.

Here are some objective tests:

1. All encoding and decoding types that are not supported are DST encoding (see the following figure);

2. After testing high-end mainstream players in the existing market, it is found that this type of encoding and decoding is not supported;
3. Through consulting engineers, we know that DST codec consumes CPU resources very much, and processors with a dominant frequency of less than 1G are basically unable to implement DST codec;
4. If there are products with the same price to support this type of encoding, we welcome your feedback;
5. For those who want to listen to this type of track, you can extract the format of. dsf/.dff through ISO. Please refer to the tutorial link:Click here

After our technical evaluation, combined with the performance and stability of the current platform, we finally decided to give up DST. Thank you again for your support for Feiao!
