ASIO v K Mixer v Kernel Streaming

Uncategorised By May 06, 2009

Computer audio seems to generate emotions when discussing what products to use that really are odd. Ideally one would take a computer, connect a good DAC and play one’s favourite music using one’s favourite app.

If only it were that simple. The more I experiment the more I realise that CA is absolutely similar to analog audio or indeed any audio when taken seriously. Every change is audible.

Of course, just because a change is audible doesn’t mean it matters.

The expression bandied about on forums about Computer Audio is bit transparent. The theory is simple: it’s getting the bits from the Hard Drive out of the computer without them being manipulated/changed in any way.

I’ve tried many music playing apps and they all seem to sound subtly different. Even different releases of iTunes are reported to sort different. Life is far to short to bother to try different releases. As they say tried it once and didn’t like it.

For convenience for quick playback I tend to use VLC www.videolan.org. It seems to play almost everything audio and video and can even stream stuff over my network. It works well for Radio Paradise too.

Times Online reports younger music fans deaf

Jonathan Berger, Professor of Music at Stanford University, California has theorised that young people are getting used to the sound of MP3s to the point where they are beginning to prefer the sound . For the past eight years his students have taken part in an experiment in which they listen to songs in a variety of different forms, including MP3s. “I found not only that MP3s were not thought of as low quality, but over time there was a rise in preference for MP3s,” Professor Berger said.

Another DacMagic power supply trial

Uncategorised By May 04, 2009

Decided to use Fleetwood Mac’s Rumours, but slightly more unusually the DVD-A rip so the source is 24/96. Unlike quite a few DVD-A’s this one appears to have some content above 22k. Amazing though that given the total available dynamic range they still needed to ‘clip’ the recording. Still sounds rather good though.
To start I compared the standard power supply with the MaplinL54BR. Pleasant surprise, the Maplin delivers a subtlety of delivery that doesn’t emphasise any particular instruments. The original in comparison seems to make the bass line and the hi-hat a little more obvious in the mix of Dreams and decreases the importance of Stevie Nick’s voice.

Another power supply for the Cambridge Dacmagic

Uncategorised By May 02, 2009

I’ve been reading good reports on various fora of using a 240 to 12V AC transformer from Maplin as a relacement power supply for the Dacmagic. It’s a 36VA tranny in a plastic case with a captive 2 core mains cable and a selection of pluggable DC plugs. It’s Maplin part number L54BR. It costs £15.

I’ve picked up one locally so reports of some listening results very soon.

Ripping and Computer Audio

Uncategorised By Apr 20, 2009

The two subjects of CD Ripping and Computer Audio seem to be the most contentious around in the world of audio now. Theory one, is that it’s possible to get good sound from a computer feeding a DAC. The debate tends to be as much around whether a Mac is better than a PC as a source as which DAC is ideal. The general feeling seems to be that a Mac Book with a DAC costing around a £1k is cable of delivering better sound that a serious or very serious CD Player. I agree a Mac and a DAC is cable of delivering a very good sound – but not a great one.

HDMI cable silences my listening room

Uncategorised By Apr 14, 2009

The experiment was to move the PC outside my listening room and then to use a 5m Chord HDMI and 5m USB cables to control and monitor the PC.
The worry was running a good monitor at 1920 by 1200 over a 5m HDMI cable. Would the image quality be reduced? The image was absolutely fine and so much so that I temporarily tried a 10 m cable which worked just as well.

Behringer SRC2496

Uncategorised By Feb 07, 2009

The Behringer SRC2496 has got to be the best value DAC around.  Mine cost £99 delivered.  Not only is it a good value DAC that upsamples (if you wish it to) it is also an 24/96 Analog to Digital converter. I’ve started to experiment with digitally recording vinyl.  Absolutely fascinating. I’d always assumed that digitally recording vinyl would bring the…
