music problem with ps3 3.01 update

[ironsword]

My imported music on my ps3 was decoded as 7.1 mult pcm on my receiver. The update that I had was 2.60 and it was real loud. When I updated the ps3 to 3.01, the reciever was 7.1 mult pcm and then clicked over to pcm only. I was fine with it, until I listened to my tracks. The music was much lower and I had to turn my reciever up more. It did the same to one of my older blu-ray movies (oldboy). It wouldn't decode into the 5.1 mult pcm english. The reciever clicked over to 5.1 pcm. Do I have it on some wrong seting on the music or something or should I reset the whole system and update the 2.60 blu-ray media disc from (under world 3). Can someone help me, your input would be very appreciated.

a SACD multi-channel on PS3 has PCM. It's different frequency technology SACD is 1bit 2822.4 kHZ and PCM is 24bit 1.754 kHz cause DSD to converter to PCM degrade sound and lower dynamic range.

DSD give dynamic range is 120 db converter to PCM is 27 db


pure direct sound on use A/O putout analog for stereo

Don't use PCM for show display on A/V receiver.
use mode : Stereo 2-channel.


Super Audio CD-wikipedia
DSD is 1-bit, has a sampling rate of 2.8224 MHz, and makes use of noise shaping quantization techniques in order to push 1-bit quantization noise up to inaudible ultrasonic frequencies. This gives the format a greater dynamic range and wider frequency response than the CD. The SACD format is capable of delivering a dynamic range of 120 dB from 20 Hz to 20 kHz and an extended frequency response up to 100 kHz, although most currently available players list an upper limit of 80–90 kHz.

The process of creating a DSD signal is conceptually similar to taking a 1-bit delta-sigma analog-to-digital (A/D) converter and removing the decimator, which converts the 1-bit bitstream into multibit PCM. Instead, the 1-bit signal is recorded directly and in theory only requires a lowpass filter to reconstruct the original analog waveform. In reality it is a little more complex, and the analogy is incomplete in that 1-bit sigma-delta converters are these days rather unusual, one reason being that a 1-bit signal cannot be dithered properly: most modern sigma-delta converters are multibit.

Because of the nature of sigma-delta converters, one cannot make a direct comparison between DSD and PCM. An approximation is possible, though, and would place DSD in some aspects comparable to a PCM format that has a bit depth of 20 bits and a sampling frequency of 96 kHz [2]. PCM sampled at 24 bits provides a (theoretical) additional 24 dB of dynamic range.

Because it has been extremely difficult to carry out DSP operations (for example performing EQ, balance, panning and other changes in the digital domain) in a 1-bit environment, and because of the prevalence of studio equipment such as Pro Tools, which is solely PCM-based, the vast majority of SACDs — especially rock and contemporary music which relies on multitrack techniques — are in fact mixed in PCM (or mixed analog and recorded on PCM recorders) and then converted to DSD for SACD mastering.

To address some of these issues, a new studio format has been developed, usually referred to as "DSD-wide", which retains standard DSD's high sample rate but uses an 8-bit, rather than single-bit digital word length, but still relies heavily on the noise shaping principle. It becomes almost the same as PCM (it's sometimes disparagingly referred to as "PCM-narrow") but has the added benefit of making DSP operations in the studio a great deal more practical. The main difference is that "DSD-wide" still retains 2.8224 MHz (64Fs) sampling frequency while the highest frequency in which PCM is being edited is 352.8 kHz (8Fs). The "DSD-wide" signal is down-converted to regular DSD for SACD mastering. As a result of this technique and other developments there are now a few digital audio workstations (DAWs) that operate, or can operate, in the DSD domain, notably Pyramix and some SADiE systems.

Another format for DSD editing is DXD (Digital eXtreme Definition), a "PCM-like" signal with 24-bit resolution sampled at 352.8 kHz.

Note that high-resolution PCM (DVD-Audio, HD DVD and Blu-ray Disc) and DSD (SACD) may still technically differ at high frequencies. A reconstruction filter is typically used in PCM decoding systems, much the same way that bandwidth-limiting filters are normally used in PCM encoding systems. Any error or unwanted artifact introduced by such filters will typically affect the end-result. If the filter designer choose a wide, flat passband, then the length of the impulse response will inevitably increase (Time-domain analysis of filters). A claimed advantage of DSD is that product designers commonly choose to have no filtering, or modest filtering. Instead DSD leads to constant high levels of noise at these frequencies. DSD's dynamic range decreases quickly at frequencies over 20 kHz due to the use of strong noise shaping techniques which push the noise out of the audio band resulting in a rising noise floor just above 20 kHz. PCM's dynamic range, on the other hand, is the same at all frequencies. (Some high-end SACD players employ an optional low-pass filter set at 30 kHz for compatibility and safety reasons, suitable for situations where amplifiers or loudspeakers can't deliver an undistorted output if noise above 30 kHz is present in the signal.)

Thank you for your wisdom Opips2. I never thought of it in that way.
By the way, I see that you have the highlander blu-ray. We don't have that here. Way Cool!!!
Nice setup to.

My favourite movie Highlander is cool sword hunter for prize.
It's steelbook blu-ray.

Thanks ironsword.
