Upsampling 16-bit / 44.1 Khz Music To Enhance It Options

[Sam Ash]

Hi all, just found this site (very interesting !) and am quite pleased to be a new member.I am quite interested to try and up-sample my normal music files (AIFF/WAVE - 16 bit, 44.1 Khz) to higher specs eg. 24 bit, 96 Khz or 192 Khz using Mac OS X based software that is specialised to do this kind of stuff. Does anyone know of any really good up-sampling software for the Mac ?

Once I manage to upsample them, I can burn DVD-Audio discs and play them through my Denon DVD1940 player which is compliant with DVD-A and SACD discs, it has a 192 kHz / 24-Bit (Burr-Brown DSD1608) 8-channel Audio D/A converter. My DVD player is connected to my A/V receiver (Onkyo TX-SR606). This is a good receiver but has no sonic up-sampling ability like some of the higher end Receivers such as Cambridge Audio which have the Q5 up-sampling technology (Highly rated) by Anagram Technologies of Switzerland.

I am using full range KEF speakers and have spent quite a bit of money on getting decent interconnects to maintain good signal quality between devices in order to prevent any loss in sound quality.

So, all in all, my intention is to be able to up-sample all my music to 24 bit / 192 Khz using the best up-sampling software on the Mac.I could then burn the up-sampled files on DVD-Audio discs for play-back on my player.

Has anyone attempted this ? Any suggestions on good Sampling conversion software for the Mac ? - I came across "Sample Manager" by Audiofile Engineering. They use a sample converter made by Izotope which apparently is supposed to be very good. Does anyone know about this or have any experience with it ?

I know the fact that decent audio up-sampling technology does make a difference, I just need input from audio experts or enthusiasts.

Any advice and input will be appreciated.

Sam

... juts found this nice little "how to" so you can make some decent playback discs ... for backup and playback on better stereos. = "Burning downloaded music onto DVD-A" = http://www.linnrecords.com/linn-help-downl...c-onto-DVD.aspx

Jim /Eddy,

Thank you for your response. Maybe you could try this product and tell me what you think about the up-sampling ability. You can download a fully working demo version that works for 15 days here (trial version) :-

I used this software to upsample some of my 16 bit, 44.1 Khz music files but was unable to burn them onto a DVD-Audio disc to test them out in my DVD-Audio compatible DVD player that is part of my music/home cinema set-up. Apparently I use Mac computers and am unable to find DVD-A authoring software.

There is DVD-A authoring software for the PC, here is the link:-

Jim, maybe some of your students can give this a trial run and evaluate the end-results. It would be nice to get a down-to-earth opinion on its real world performance.

Apparently, Sample Manager software (by Audiofile Engineering) incorporates technology by Izotope which is highly rated. Here is some information:-

The Izotope SRC
The iZotope 64-bit SRC™ utilizes a hyrbrid algorithm providing the highest quality and most customizable resampling available on the market today.

MBIT+
iZotope's MBIT+™ dithering algorithm features psychoacoustic noise shaping, based on research with actual musical material, making it the best sounding dither on the market.
