leenuss Posted March 8, 2005 Report Share Posted March 8, 2005 Recording in PCM on my MZ-NH700.... Is it 16 bit 44.1 kHz only? What's the specifications of the Hi-MD format? Nowadays I'm doing mixdown of my music in 24 bit 48 kHz... Would I be able to transfer these wave files to OpenMG PCM? Would the track be converted into 16 bit 44.1 or would it stay untouched? I remember my seven year old MZ-R30 could record in 32, 44.1 and 48 kHz but only play back in 44.1 kHz. Quote Link to comment Share on other sites More sharing options...
dex Otaku Posted March 8, 2005 Report Share Posted March 8, 2005 All MD and HiMD recordings are sampled at [or actually, resampled to] 44.1kHz.PCM mode is 16-bit stereo only, same as CD.If you throw your tracks at SS or your HiMD via optical in using 24-bit/48kHz, it will all be resampled to 44.1kHz. In fact, all streams, even those which are 44.1kHz fs already, are resampled to 44.1kHz when using the optical in.ATRAC at the very least [sP mode] and likely all of the ATRAC/3/plus formats are capable of directly encoding >16-bit material, though I'm honestly not sure whether the SS codecs are limited to 16-bit [in which case everything would be requantised before encoding]. It is highly likely that the SS decoder, at the very least, is limited to 16-bit PCM decoding [as evidenced by copying its output using Total Recorder, and its lack of bit-depth settings regardless of what your sound system supports].The information re: sampling rate &c. is in your manual, btw.

Guest NRen2k5 Posted March 26, 2005 Report Share Posted March 26, 2005 AFAIK, SS has *issues* with audio higher than 16-bit. The issues arise from using FFDshow, which for some reason makes you use a plug-in called MAD to decode MP3. There is no noticeable increase in playback quality of MP3, but it is upsampled ot 24- or 32-bit. These 24- and 32-bit streams will be interpreted fine by SS sometimes, and lock it up other times.

Although it is possible, in theory. Quote Link to comment Share on other sites More sharing options...
Guest NRen2k5 Posted April 13, 2005 Report Share Posted April 13, 2005 These, however, are just issues with how the encoder is written to accept input and deliver output.Internally, perceptual lossy encoders like MP3 and ATRAC don't have any bit depth.

Or, in the case of CBR, it allocates the most bits to the blocks that needs to the most and fewer bits to less "important" blocks in a perceptual sense (both in the time and in the frequency domain). That's what I meant with bit-depth. Quote Link to comment Share on other sites More sharing options...
dex Otaku Posted April 15, 2005 Report Share Posted April 15, 2005 NRen2k5 means bit depth in the same way that I generally do - linear bit depth, as applies only to PCM. Transform-based codecs do not have a bit depth in this sense. Quote Link to comment Share on other sites More sharing options...
