However, most of those MULTIBIT DACs were designed having to work with digital filter chip through an interface we called "PCM", which transmits left and right data simultaneously. « Many people still like the sound of traditional MULTIBIT audio DACs, such as AD1865/62, PCM1704/02, PCM63, TDA1541/A, and many others, because they convert digital music into analog in a different way than popular DELTA-SIGMA DACs. They also have made a board which is an I2S to PCM converter : ….board.htmlĪs they speak better than me (extract from the datashit of the board) : An I2S Fifo kit, constituate of the fifo board, a clock and an isolator : ….itter.html I know that an alsa driver for i2s has been written, but i don't know if it's work with this?Īnother question, at diyaudio they are making a dac constituate of some separate (different projects…) boards. If i understand it right we just have to connect the P5 headers of our pi to this, to obtain a good i2s outpout for hifi purpose, compatible with a growing number of equipement (for now, one of the only music server compatible is the sonore rendu : and it cost nerly 1600€ with this i2s hdmi option, and also a growing list of dac)
Some manufacturer propose compatible board for this : ….y/I2S.html ….-8404.html I want to make it a sound server with remote control (android app) and use it's i2s outpout, because this infercace is an emergent hifi standart, since psaudio propose an open inferface with an hdmi cable for i2s : ….audio.html
