lucretius Posted May 5, 2020 Share Posted May 5, 2020 The Best Settings List The purpose of this thread is to publish the “best” DHNRDS-DA decoder settings for each album release, so that anyone with his/her own copy of the music will be able to apply the settings using the decoder software. Jump to post #2 for the semi-official list. The best settings entered by John Dyson are not official entries yet but rather are simply cut and paste from his manually maintained test table -- his settings are continually improving along with each new version of the DHNRDS-DA decoder. Forum members collaborating on best settings should submit entries to the list (via post to this thread) in the following format: FIELD VALUE Artist: Supertramp Title (Format): Breakfast in America (CD) Original Year: 1979 Label: A&M Records Release Country (Year): Argentina (1985) Catalog Number: 393 708-2 Barcode: 82839370820 Number of Tracks: 10 External Links: https://www.discogs.com/Supertramp-Breakfast-In-America/release/12834576 Submitted By: @John Dyson DA Commands: --fb=4 --tone=-14.425 --wof=1.19 Post EQ with SoX: treble -1.5 9k 0.50q treble -1.5 9k 0.8409q Comments: It is not necessary to complete every field but the more, the better (to identify the source release). Occasionally, I will combine the entries and publish the updated list in post #2 in this thread. Background DHNRDS stands for DYSON-HESS Noise Reduction Decoder System. The project was conceived to produce a family of software decoders to correct the ills of audio recordings encoded with various noise reduction systems (e.g. Dolby A, Dolby B, Dolby C, dbx type I, dbx type II, and Telcom C4). The project and its products are the work of John S. Dyson and Richard L. Hess. As many of you know, Mr. Dyson, a member of Audiophile Style, is the software developer. The DA in ‘DHNRDS-DA” is short for Dolby A. The DA decoder is the first software decoder to be produced by the DHNRDS project. It is software that provides high quality decoding of music where the (analog) master tapes or other media1 were encoded with Dolby A. The DA decoder operates in one of two modes: (1) The raw/true Dolby A decoder mode, called ‘DA mode’, and (2) the FeralA2 mode, called ‘FA mode’. In DA mode, the (command line) decoder runs without any corrective EQ. The DA mode is intended for professional use in the studio and can be used as a substitute for using actual Dolby A hardware decoders. In FA mode, the decoder runs with corrective EQ to undo the FeralA2 encoding, i.e. where the (analog) master tapes were encoded with Dolby A and subsequent CD releases were mastered from these original master tapes without Dolby A decoding. The FA mode is intended for use by audiophiles. For more background on the decoder software, see: 1. Apparently, some mastering engineers have used Dolby A hardware encoders as selectable mode multi-band compressors. For example, engineers modded Dolby A hardware units to disable the lower bands so that only the high-frequency portion of the signal is compressed, giving more air to vocals. 2. FeralA, a term coined by Mr. Dyson, refers to undecoded Dolby A recordings that have been subsequently processed (EQ’ed) for mastering of CDs. Note that there exists very few CDs that suffer from pure unmodified encoded Dolby A (i.e. no subsequent EQ). John Dyson 1 mQa is dead! Link to comment

John Dyson Posted May 5, 2020 Share Posted May 5, 2020 I intend to start adding some entries to the list in a day or so... Today, I am nailing-down the settings for a few recordings being used for testing & review. So -- I'll definitely be contributing to this list and 150% in favor of doing this now. I am so glad that @lucretius is getting this started. My commitment: The decoder is 'stable' in the sense that settings that work now will also work the same in the future. Any changes will be add-ons, currently available standard settings will not be removed. Some features might be added, but won't interfere with currently expected behavior. That is: documented decoding behavior will be consistent in the future. @Lucretius timing is perfect. Add-on: when I do a contribution along with everyone else, I want EVERYONE to know that it should okay to create alternative settings suggestions. Some of the variability might result from subtle differences in the recordings, others might simply be matters of 'taste' or 'hearing'. The group/moderator/etc might either choose to negotiate the variants or maybe just document multiple decoding choices? As anyone knows who uses the decoder, sometimes two settings sound similar -- there are SOMETIMES multiple 'best' choices. This quandry is especially real for my results - sometimes choices might eccentric because of extreme variability in hearing ability. I would rather see multiple versions of 'reasonable' settings instead of someone suppressing a strongly held opinion. We should not dismiss a differing opinon -- but try to understand the basis for the differences. John Link to comment

John Dyson Posted May 6, 2020 Share Posted May 6, 2020 When I looked at the postEQ field -- I realized something important that might help people when they do their own decoding & determining the EQ. Since this is about using the decoding for a given recording -- I have a few comments about that process. I do suggest AUTOMATING your process as much as feasible. Here is a suggestion about keeping the 'before EQ' version: When adding post EQ, consider keeping your original 'before EQ'/direct output from decoder version around also. My own process is usually to either create an 88.2k 'floating point' .wav file or a '24 bit signed integer' .flac file before EQ. I do the EQ and conversion to the final/listening format in a 2nd pass after very careful review and listening. Your final output format might depend on the quality of the recording, and for me, is usually 88.2k 24bit signed integer or 48k 24bit signed integer. If you need to make a smaller file for your brother/sister or your portable listening, then when you start with one of these two -- you are in a perfect position to create almost anything. Since I almost always keep the original 88.2k .flac or .wav file produced directly by the decoding operation, then I can always produce that 'perfect' 88.2k/24bit version if I really want -- even if I might normally produce only a 48k version for certain material. (I often pipe directly to sox, and let sox do the conversion to 'flac'. Warning -- that SOX .flac conversion loses the in-file metadata!!!)* * Because of the loss of metadata when using sox for conversion, I am seriously considering an optional shared library link to a .flac library, but I really need to be careful about licensing because the decoder is not free source-code software yet. It is free to use, but I do not want to disclose source until I can mathematically defend the tricky parts. What I am trying to say is keep your direct decoder output version if you can. Stash the 'unmolested' away in your archives or wherever you put things away. The reason is that a good decode can take many minutes, but another EQ try only takes seconds. Don't lose the original decoder output, just in case the EQ needs to be retried. Re-decoding something is something that can take very significant amounts of, unless you want to try different settings for decoding. EQ is trickier for me, because when decoding, the recording often gives stronger hints about the best settings. EQ is more based on taste, but SOMETIMES recordings give hints for EQ also. You'll see that my upcoming Breakfast in America decode does use a little more EQ than my personal guidelines. There were serious and important reasons for my choice -- and I'll note them. My own rule for EQ -- have real reasons, based on perception, why I did post decoding EQ. * it is perfectly okay to do post-decoding EQ for taste reasons. My reason for avoiding doing much EQ is that my own taste is not the same as everyone else :-). John Link to comment
John Dyson Posted May 6, 2020 Share Posted May 6, 2020 This might be a little premature, but I am adding the first 3 Supertramp decodes.

John Dyson Posted May 7, 2020 Share Posted May 7, 2020 7 hours ago, lucretius said: Hi John, Are those SoX effects pre or post DA decoding? Any EQ is post decoding, and my previous comments about output IEC were wrong. My posted decoding values stand as 'best' so far. All pre-decoding EQ is done inside of the decoder. I try to keep the post decoding EQ down below 1.5dB, even though 'Breakfast' was a total of -2.25dB, which is on the strong side. I kept getting complaints about the HF being too strong. If you see me doing THAT much EQ, it doesn't result from my own opinion. My habit and listening tests see some recordings needing between -0.75 and -1.5dB -- not sure what the reason is -- I don't do that unless I hear a defect. Explanation about the IEC: initially, the results sounded good, tamed the sound. This morning -- with better "virgin' morning hearing, the sound was deadened, and the excessive result was found on the spectogram. When doing comparisons against my reference recordings, where the DHNRDS might be more bright -- the other reference recordings sound like the DolbyA HW 'fog' more than relative suppression of highs. The DHNRDS retains dynamics, so might appear to be a bit more intense than reference recordings. John lucretius 1 Link to comment

It is slow because it doesn't emulate a DolbyA, but does lots more to avoid distortion. It is intended for archives, less-so day to day listening.

John Dyson Posted May 8, 2020 Share Posted May 8, 2020 The first ABBA decode. This is as good/clean as my results have ever been. The decoder settings are based on distortion, not EQ - so you might wish a different EQ choice. WIth the settings below, you can use whatever EQ you want, and the sound will remain very clean. This is an early ABBA CD -- most of the early ABBA CDs require very similar settings, and some require the exact same settings. More will be coming.

John Dyson Posted May 8, 2020 Share Posted May 8, 2020 Wow -- I was just getting ready to publish the 'SuperTrouper' numbers -- and was looking up/comparing my normal/quick access .flac files for the album, searching for the originals -- so I can then pull together the metadata external to the files. Lo and behold, during my comparisons, I found an AMAZINGLY, EVEN BETTER copy of SuperTrouper. I cannot believe that I missed it. You gotta realize, that back in the day I bought lots and lots of material -- for some reason I collected it, knowing that it sounded like cr*p, but also somehow looked into the future and realized that I could eventually clean the recordings up... The version that I have been 'proud' of up until now, has a pretty darned good peak-RMS of 20,67, but this just found version sitting, hidden in my archives has a peak-RMS of 21.10. The difference doesn't seem like a lot, but it makes a substantial difference in quality, especially when decoding FeralA. (A lot of 'normal' copies of SuperTrouper have 15-18dB peak-RMS -- very significantly compressed. The 'Complete' Studio recordings have peak-RMS of 13dB!!!) Almost every time I go back through my collection, and review the recordings by explicit measurment, it seems like I find something very significantly better!!! WOW!!! It appears that the 'super-duper' version benefits from slightly different parameters, so I'll probably publish the parameters for both versions. The SuperDuper version is PolyGram/PolyDor OZ, 800 023-2. John Link to comment

John Dyson Posted May 10, 2020 Share Posted May 10, 2020 6 hours ago, jabbr said: Are there settings that go along with this? Yes, more, new, easy-to-use decoding parameters are coming along with the new decoder update. You CAN use the V1.4.1F decoder to decode it nicely, but the V1.4.2A (or B) decoder has two new subfeatures that allow digging deeper into the signal. This is why I stopped publishing new parameters for now. Richard asked for some more features (e.g. an .ini file), so I decided to delay until Sunday night so that I don't keep stuttering releases. With the addition of the new settings, I intend that V1.4.2A contains the last new mode until a significant improvement is needed. I believe that it is time to freeze, because the quality has been very good, and an expanding feature set can contribute to more damage/confusion than help. On very extreme cases, I can explain the internal commands on a on-on-one basis. It is not simple to map the 'sound' to an internal setting like it is when using the '--fa' series of commands. This is why it is important that we all nurture and protect the '--fa' series of commands (like '--fa, --fb, --fc, and --fD.) ALL of the previous published parameters are good, very good. However, I decided to expose another previously hidden capability which benefits some of ABBA, Carly Simon and MAYBE EVEN Supertramp. It might be easier to resolve a problem while decoding Supertramp with the new user accessible feature. So, the new modes enable a simple tweak, similar to the 'a' and 'b', but do something previously unavailable in the '--fa' command series. (Note that I eat my own 'dog food', andI restrict my normal usage to the suggested command set -- I use the internal controls only to consider upgrades to the standard command set.) (There is incredible flexibility in the general command line interface, but I am keeping the --fa, --fb, --fc and --fD commands at a sane level of complexity -- only adding capabilities when there is noticeable benefit.) Manually controlling the decoder needs synchronization of various frequencies/Q values/gains and EQ/filter types. Anyone with deep audio experience could directly control it, but it quickly becomes complex and UNFUN. I never use the low level commands nowadays unless I am testing for upgrading the normal '--fa' based commands. John Link to comment
John Dyson Posted May 10, 2020 Share Posted May 10, 2020 6 hours ago, jabbr said: Those settings with --wof= ? .8409 I left --wof=1.0 (or the default) because I couldn't justify a change. This is one of those 'fine edged' things that I am not 100% comfortable adjusting unless I have proof. Previously, I had modified the stereo image beyond the default -- but recently re-visited the matter. Background on the stereo image -- it is a very subtle thing that spent a lot of my time. When developing the decoder, I knew that the stereo image was messed up, but not sure what to do about it. At one time, I tried modifying it on 'before decoding', and it sometimes worked okay. Then, I tried 'after decoding', and it worked okay on other recordings. I couldn't get 'most' recordings to do the right thing, until about a few months ago, when I had a Eureka that 'MAYBE' both need to be modified all of the time, by about sqrt(2) -- I was right. Everything always came out plausibly correct (no severe shifths between foreground and background) when doing both. However, sometimes the image was still messed up. I got into the habit (a bad one) of modifying the image by default, because I was used to doing it. Sometimes, the default is a good value. A good example of a case where the image MUST be modified -- the Led Zeppelin album that I recently did -- it sucks unless the setting is wof=1.19... It isn't happy with 1.10 and isn't happy with 1.41 -- it really likes 1.19. This, along with other things, validated my fractional power of 2 approach. John jabbr 1 Link to comment
John Dyson Posted May 10, 2020 Share Posted May 10, 2020 Take a look at the FeralA decoder announcements -- new decoder, well worth it. All known 'compromises' are now fixed but previous decoder settings are still 100% valid. Mostly, we just have more control. Personal note: family member getting operation, might be in and out, so a LITTLE less responsive for the next few days. Believe me -- this new version V1.4.2A is really worth it. If there will be stuttered releases (something in the next few days), only because of uncaught bugs. This code is REALLY NEW!!! John Link to comment
