we want to use esp32 + sgtl5000 in the project, we want to mix up to 5 mp3 file read from sdcard or http stream and mix them together and send to output headphone jack we want to use the features as in teensyduino but without any external chip. just esp32 and sgtl5000 (or you may suggest us different cheaper audio decoder chip then vs1053 series) features we expect: - decode any kind of mp3 file (stereo or mono also) - load one ore more mp3 file at the same time and mix them - change volume of any input mp3 file and change mixed output volume - crossfade 2 mp3 files to mixer - fade any of loaded mp3 - get left and right vumeter values - read from sdcard - read from http mp3 stream (like icecast or shoutcast) - play, pause, stop any source - get position and duration of loaded mp3 files for each - add new file to mixer (when any mp3 finished, we want to add new file) - if possible, but not mandatory, compressor and limiter filter to output and each mp3 (or kind of gain control) you are free to use RTOS or arduino libraries.. after this project, we will add ethernet, rtc , usb etc.. and if you capable of them also, we will open a new project for them ..

Hello, I represent Anvation Labs and we are SMART prototyping and production as a service company in the field of embedded systems. As I understand, you need a wifi connected audio mixer device capable of mixing, fading, amplifying multiple audio files from sdcard or an audio stream. I assume, you would like to control this from a remote device (a laptop or mobile) in the same wifi or over internet. This is quite interesting, and it is like one of the projects we had executed, where we had developed a multi-channel audio mixer on an embedded MCU. I have experience in audio processing, decoding of various audio format and codecs. I can propose you a cheaper option for your codec with respect to sgtl5000 which I have already worked with. Please initiate a chat to discuss on your project further. Thank you.
