On a Pi3 with a 24-bit FLAC file at 44.1KHz and an I2S attached HAT DAC, resamplig to 32-bit/352.8KHz uses negligible resources, something of the order of a few percent. More advanced methods (such as Sox) uses complex regression functions to predict the original inter-sample values.ĭepending on which Pi and DAC you have, it's almost a no-brainer. In each two consecutive sameples, it will insert average values of the two consecutive sample values. Good resampling methods (such as with Sox high quality) will attempt to predict the original sound between the inter-sample gap correctly and insert new samples based on the prediction.Ī simple method to upsample from 44.1KHz to 88.2KHz can use simple averages of two consecutive samples. If you do, resampling to a higher rate is more than just stuffing more samples between existing samples. If you don't resample, Moode will play in the 'native' format of your audio file. Thnx in advance! I hope I didn't confuse you In short I want to have the drives spin all the time while the rasp is in use, and go to sleep when I shut (or Sleep if possible) down Moode! While the desktop drive goes to sleep after some time if not in use, or shuts down after I shut dow the Moode, the other spins all the time!ġ) I want is to ask is if there is a way to make the Moode go to sleep mode (with the drives connected on it) when not in use so that it will not be nessesary to unplug and replug it in order to use it again after it's shut down!Ģ) is there a way to make the connected drives NOT to go in to sleep mode while the machine is in use? For example, after a while of radio listening, the drive goes to sleep mode. One desktop 1TB Seagate with self power and another portable 320GB connected through an active hub to the rasp. I want to use the Raspi SSH app on my android phone to make some comands for the Moode to shut down when I don't use it without having to use my computer.Īppart from the ip adress I need Username, Password, and Port in order to make the SSH app connec with the Moode.
