Re: Can I change 1053 playback speed with a DDS as XTAL?

Hello! I made a 100 second m4a file with 44.1kHz. When playing it back, the sample count register is at about 4405286 (+/-200) at the end, so it somehow missed some samples. However, the playback time of rendered output is exactly 100 seconds long (I recorded the 1053 output with a DAW to verify). W...

Re: Can I change 1053 playback speed with a DDS as XTAL?

Hello! It's year-end break time, so finally I got time for this project again. :) To whom it may concern, I think there is a mistake in the 1053b patched PDF on page 12: unsigned long Read32BitsFromSCI(unsigned short memAddr) { unsigned short msbV1, lsb, msbV2; WriteVS10xxRegister(SCI_WRAMADDR, addr...

Re: vs1005 audio decoder, goto spot in audiofile in milliseconds

Hello! As you have notived, we have implemented the go to functionality with a granularity of one second. The reason for this is that for some audio formats, finding an accurate location is either difficult or time-consuming, so even the one second granularity should be considered a "nice wish", not...

Re: Retrieving stereo levels?

Hello Brek, so you want to know the signal level for the audio that is being played back? To my knowledge that data isn't directly available anywhere. You could, however, get a pretty accurate estimate if you'd just read the DAC registers at regular intervals, e.g. 1000 times per second, then calcul...

Re: Filtering white noise in vs1063a

Hello! From your code it isn't clear if you use the line input or microphone input, although it sounds like you are using the microphone input. If you are using the microphone input (SM_LINE1 = 0 in register SCI_MODE), then this amount of background noise is normal, especially with your 20 dB digita...
