I always struggle with the synchronization of different digital devices, and I believe the new Cirrus Logic CS2600 can be the solution I am looking for: IIUC, it can take an external word clock (or a MCLK, but I am interested in the former) and generate a "quality" set of I2S clocks synchronous...

Some background: These last weeks i have been thinking on building a headphone amplifier as part of a larger project (USB interface). I thought that i could use the CS43131 inside my Meizu Hifi Non Pro. But i wanted to do it with output opamps to have more power available, as this is going to be...

I wonder if someone ever looked into DIY a multichannel USB bridge using the Com True CT7601PH. I am asking because all the parts seem to be available yet i cannot find one single diy project online: ComTrue website has available: - Drivers - Instructions and detailed schematic of the...

Hello, I am having a hard time to decide which high power PSU I get for a diy multichannel TPA3255 amp I am building. The project consists on 4 TPA3255 boards, some stereo some mono, hence the desire for a decent power supply. The contenders are: Mean Well GST360B36-C6P - 36VDC 10A at ca. 110...

Hello, i was very happy a couple of days ago when i finished assembling a balanced to toslink ADC based on the new ES9826q. The objective is very low cost, hardware mode, usable to measure the frequency response of my diy amps (have added voltage divider resistors to the input) and toslink...

Hi, I have spent some time looking into these cheapo black boxes from Aliexpress that claim to decode DTS AC3 etc from toslink, and give you 5.1 audio without using any AVR or similar. I am talking about these: The objective for me is to build a very small (needs to fit inside the enclosure...

Hi, I am looking for this board: But it must be that exact one, NOT this other one: Both these and yet other similar sell in AliExpress for 15 euros, either as the naked board or most often inside an enclosure like this: The problem is that no matter what the picture is, no matter what the...

Hi, As a tangent from another project i recently became interested about HDMI eARC, to the point that I went and read everything about it I could find in the internet. It took me about 30 minutes. Not satisfied, i bought from Aliexpress the cheapest eARC audio extractor that I could find. It is...

It has been discussed here millions of times: you can't just use various USB DACs simultaneously to have a multichannel system because they are not synchronized and will drift apart. But yesterday watching the last video at eevblog, where he talks about crystal oscillators, he mentions what...

Since I saw this at the asianometry YouTube channel I can't take it out of my head. You can design and print (? Etch, burn, I don't even know how this is called) your own chip for as little as 300$. As I understand it, they collect projects from different participants and at the end of the...

hi, I have a DIY amp project going on and have a couple of square cm left on a PCB (not the amp pcb). I thought it could be neat to use that extra space to add a simple ADC to measure mainly amplifier frequency response and maybe some other random measurements without risking my good ADC. I...

Hey guys, This is a strange question for ASR, but i have been all the weekend trying to find out and ran our of resources, so I thought I would try my luck here as there are quite a few knowledgeable folks. Since a couple of weeks, I am receiving verification codes to access my google account...

Dave @ EEVblog shows how physical vibration can reduce significantly the noise of power supplies. I can imagine someone trying it out :facepalm::D

Hi, I was hesitating posting this project, as i guess there will not be much interest here, but questions start to accumulate and I thought that maybe someone wants to have a look and chime in. You might recall me asking about using heat pipes in audio amplifiers. What i had in mind was this...

Hi, I am considering building a power amplifier and want it to have audio sense. I have searched a while, but could not find any solution suitable for my project. I do know Rod Elliot's Signal detecting circuit but this is a fully analog circuit that does not fit my needs...

Hi, Computer CPUs dissipate a lot of heat and from what I understand (very little) their cooling systems are very much developed and performant. I never see heat pipes assemblies in power amps (I am not interested in water cooling). Is there a reason for that or is it just that is not usually...

Hi, From time to time I buy small electronic components from AliExpress. Since this morning, I have noticed a very sharp increase in shipping costs. What used to be a few cents is now 3-4 euros. I wonder if something in my settings has changed or if this is a general thing. Has anyone...

Hello, I am in the process of reverse engineering a HDMI audio extractor to build a HDMI audio capture card. The extractor is USB powered and has two identical SOT 23-5 buck converters that provide 3.3 and 1.8V. I could not identify the parts but the pinout and circuit match, for instance...

Hi, We are in the process of defining how our new house will be. There will not be a room dedicated to home cinema and audio in general is not a priority. However, of course, i don't want to miss the chance to leave at least leave some infrastructure to facilitate having the best audio possible...

Hello, i know this is not an easy question but just in case there is someone out there with some experience with HDMI ARC. I am thinking on building a multichannel HDMI to i2s audio extractor hat for raspberry pi. The idea is to capture multichannel audio from HDMI and send it to a raspberry pi...
