And as I recall, I only exceeded 2GB with the tracks from the Honeck Strauss Elektra album in DXD. Link to comment

I guess I know too well how digital audio works to see any value in that 🙂 2 hours ago, tailspn said: BWF (Broadcast WAV) is simply a WAV file with the ability to support metadata: Looks to me that if the data is larger than 4 GB (which would be likely in case of surround version), then the player needs to support either the "link" chunk or the RF64 extension of the WAVE format: https://en.wikipedia.org/wiki/RF64. Anyone knows how widespread the support is? Link to comment

Since I did not master this RR Beethoven, I've very limited knowledge of the post processing production processes involved. But I doubt they extend much beyond 24 bits.

True. My comment was only about the value (or lack thereof) of a 32-bit file for the end user. Link to comment
ray-dude Posted February 18, 2021 Share Posted February 18, 2021 These days, I'm listening to a lot of 16fs 32 bit content (705/768kHz) as wav files. When files get bigger than 4GB, I'm splitting them into multiple parts. With players that support gapless playback (HQP, Roon, etc), this is no issue at all. The parts play as intended, even with the 4GB limitation With all this preprocessing, I appreciate being able to get content in as close to the mastering format as possible (less about information content, more about information quality after digital processing....basically the same reason the mastering system does processing in 32 bits) Rexp 1 ATT Fiber -> EdgeRouter X SFP -> Taiko Audio Extreme -> Vinnie Rossi L2i-SE w/ Level 2 DAC -> Voxativ 9.87 speakers w/ 4D drivers Link to comment

It will take a few days to appear on the site for selection, as the site is not currently programmed to offer multiple DXD deliverables. Two-channel only, so far.

There is of course support for 24 bit FLAC of the same sample rate in either 5 or 6 (5.1) channel. It's no problem to make, or play (in JRiver at least) this 32 bit surround file, it just won't load into our AWS delivery servers. The format is unsupported, returning an error stating unsupported file header. For those set upon playing this 32 bit 5 channel WAV file, I'll send you a direct Dropbox link if you purchase the same FR741 5 channel FLAC from NativeDSD.com. Just send me a mail at [email protected]. Fair enough? Thanks, Tom blue2 1 Link to comment
PAP Posted March 4, 2021 Author Share Posted March 4, 2021 Is 32bit really better than 24bit. And is the 32bit files that are starting appear, what they call floating point? Link to comment
Popular Post tailspn Posted March 4, 2021 Popular Post Share Posted March 4, 2021 The short answer to your first question of a 32 bit PCM being better than a 24 bit is no as a delivery product. As explained in this Sound Devices article: https://www.sounddevices.com/32-bit-float-files-explained/ 24 bit PCM fixed point supports a dynamic range of 144dB, where the best of acoustic recordings rarely exceed less than half that dynamic range. 32 bits float (actually 64 bit fixed point in the best Digital Audio Workstations (DAW)) is supported for post processing digital signal processing (DSP) math bit growth during processing. Upon post processing (channel mixing and balancing, and/or sweetening) completion, files are truncated down to 24 bit fixed point for delivery, or 32 bit floating point for archival and further processing. 32 bit content files are typically floating point, but can also be fixed point. Both 24 bit and 32 bit deliverable files are always fixed point, to be operable within a DAC. Tom Mark M and PAP 2 Link to comment

Both 24 bit and 32 bit deliverable files are always fixed point, to be operable within a DAC. Tom I read the article -- and as a user/developer of software that uses both RF64/BEXT and FP .wav files, the nuance of the convenience factor about FP files might be missed: you don't have to worry about clipping. The clipping issue is somewhat implied in the article, but my software that does *very* massive processing to undo the last-step compression used on consumer recordings, using default gains, it is almost impossible to guarantee no clipping on a signed integer file. Decreasing the liklihood of clipping requires telling the program to use at least -10dB or more gain on output. Doing things like that just seems ugly -- because clipping is still possible even with a 10dB output attenuation. Using FP files eliminates the trouble, then DAW or whatever software can be used to bring the signal back down to +- 1 (0dB peak) again. Warning: SoX internal representation is 32bit integer, so cannot deal with larger signal FP files, but I'd expect modern DAWs to work okay. Bottom line: FP can solve a lot of potential headaches and even potential time wasters during production. For distribution, FP isn't really necessary. Sometimes, during production, when really busy, not needing to worry about signal peak limits might help decrease some small amount of stress. Distributed recordings are already massaged to be at correct signal levels. Link to comment

Popular Post JoeWhip Posted July 21, 2021 Popular Post Share Posted July 21, 2021 I will be hosting a zoom call on August 4th with our Philadelphia Area Audio Group with Patricia Barber and Jim Anderson about the new album. Members of several east coast audio groups which we have been sharing virtual events have been invited to participate as well as members of the audio and jazz press. Should be fun. I will try to bang out an article about it quickly. CC has an invite if he what’s to chime in. Any questions anyone would like me to put in the queue let me know. christian u and PAP 2 Link to comment

Superb sound. Great review in hifi critic: This is about as simple a recording as you’re ever going to hear: two musicians, one microphone and each track performed live, straight to DXD recording – and it’s totally enchanting…all that spontaneity comes over in spades in this set, which has the usual Sound Liaison recording quality, plus that unmistakable sense of two musicians just bouncing off each other, improvising and making the shape of the songs up as they went along. This is as live as it gets, with a real "in the room with the musicians" impression.' —Andrew Everard, Hifi Critic PAP 1 Link to comment
