Re: HiFi audio player

Hi all am back. I've been writing my thoughts for this down while I was away. I am going to start building my dac over the next week or so. I did forget to mention I think that I have a few tenor USB to i2s converters so if I get stuck with no i2s for any length of time I can use this to get around ...

Re: HiFi audio player

The shielding will be achieved by using strips of u shaped aluminum channeling attached to the bottom of the case with plates attached either side. At the top it will meet up with the case top, and any holes that go between sections will be ran through tubes. To begin with I may pop rivet these toge...

Re: HiFi audio player

Thanks FifthQ So parts whise I think I have most of the parts I need to start. My intention is to split the tuners case into shielded sections to try and minimise noise. This may seem ott but I want areas for the following - rpi - USB modules - clock - dac - dac analogue psu - Dac psu - Rpi psu - US...

HiFi audio player

Hi All I have been looking at a HiFi audio streaming project for a while now originally using old laptop hardware with USB dac’s. When I first heard about the Pi some 9 months ago it seemed like the perfect platform to build one on. Using the I2S bus and Wolfson WM8741 DACs with a dedicated clock th...

Re: I2S: Anyone got it running?

Talking of a hardware master clock would a pink fish media flea with a tent labs clock do the job. And is so what's the input pin for the pi?

Re: Sad about removal of I2S. Why was this change made?

<t>Ok so they lost I2S by accident, that’s fine. At least with Gert’s help we may be able to get it back with a hack. If Gert will help us/me find the pins I am happy to do the mod to my board, and upload a how to video to youtube and write a wiki entry.<br/> <br/> As for the external clock I would ...

Re: High quality USB 2.0 sound card (24 bit/192 kHz)

<t>TechColab / R1ck has it right. wm8741geds is the way to go, and for those with less cash wm8740 is pin compatible and slightly down on performace (still aroung the 120db range).<br/> <br/> My gut says that if we can get the i2s working a pair of wm8741geds in dif mode will give us better quality ...
