USB DAC 128 Mk 3 from Henry Audio gives you
Fantastic sound from computer to audio system
Selvfølgelig er du glad i musikk, ellers hadde du nok ikke sittet og lest på denne siden. Da har du sikkert også lastet ned mye musikk på din egen PC eller Mac de siste årene, eller du bruker strømmetjenester.
All den digitale musikken du enten strømmer eller lagrer, kan låte utrolig levende, spenstig og dramatisk, veldig langt fra den flate og livløse lyden du får rett fra PC, men for å få musikken du spiller til å låte akkurat så overbevisende, deilig og dynamisk som bandet, produsenten og komponisten hadde i tankene og ørene, trenger du en USB DAC.
En fra Henry Audio. Den lille boksen som gjenskaper den digitale musikksamlingen til fantastisk lyd som bringer fram din indre luftgitarist, dirigent eller trommeslager, og gjør digitale musikk mer levende enn du har hørt den før. Garantert.
Henry Audios lille USB DAC 128 Mk 3 er skapt av musikkelskere med ett eneste mål for øret; å gjøre det så enkelt og rimelig som mulig å gi deg lydkvalitet som vil få deg til å klype deg i armen, som flere av verdens mest erfarne HiFi-og lydproffer har gjort allerede. Ved å gi de digitale lydfilene en solid vitamininnsprøytning av eksplosiv karakter. Hør musikken din som den var ment å låte, og få en diger dose entusiaste og fornyet musikkinteresse på kjøpet!
Musikk har aldri vært så moro siden du kjøpte ditt første stereoanlegg, og det koster slett ikke mye å få den følelsen igjen.
Det er derfor vi sier „DAC skarr´u ha“. Og selvfølgelig skal du det, ikke sant?
DAC sounds good!
Of course you like music, otherwise you wouldn’t be reading this page. You have probably downloaded a lot of music on your PC or Mac, or you use streaming services.
All this digital music which you either stream or store can sound incredibly alive, spirited and dramatic, far removed from the flat and lifeless sound you get directly from a PC. Butin order to make the music you play just as convincing, delicious and dynamic as the band, producer and composer had in mind, you will need a USB DAC.
One from Henry Audio. The little box which reproduces the digital music collection into fantastic sound, bringing forth your inner air guitarist, conductor or drummer, and makes digital music sound more alive than you have ever heard it. Guaranteed!
Henry Audio’s little USB DAC 128 Mk 3 is created by music lovers with one goal in ear; to make it as easy and affordable as possible to give you a sound quality which will make you pinch yourself, as several of the world’s most experienced HiFi and audio professionals already have. By giving the digital audio files a solid vitamin injection of the most explosive kind. Hear your music like it was meant to sound and get a huge dose of enthusiasm and revived music interest as part of the bargain!
Music wasn’t this fun since you bought your first stereo kit, and it doesn’t cost much to get that feeling again.
This is why we say „DAC sounds good“

Q: I am a programmer. Where do I start?
A: Visit the project links above and join both SDR-Widget and Audio-Widget mailing lists. There is very little cross-posting. The SDR-Widget Wiki is a good starting point. It explais the git repository and other details.
Q: Which coding efforts are wanted?
A: The MCU firmware is stable. But there may be features you need which we haven’t thought of. Our most pressing issue right now is Windows driver support. If you’re familiar with Audio processing / USB / Windows drivers / Linux drivers, or related things, please join our efforts.
Q: I like analog tweaking. Where do I start?
A: The Henry Audio USB DAC 128 mkII is a good starting ponint for analog tinkerers. Feel free to mod it! Please feed your knowledge back to the group members.
Q: I’d like to reuse the PCB designs for a commercial project. What do I do?
A: Contact me at firstname.lastname@example.org. I have years of experience in commercial PCB design and manufacturing. We’ll sort something out!
Q: The diyaudio thread is huge. Where do I look?
