Arduino library to play MOD, WAV, FLAC, MIDI, RTTTL, MP3, and AAC files on I2S DACs or with a software emulated delta-sigma DAC on the ESP8266 and ESP32
Hello,
I made a kitchen radio with 20 (soon 5 x 20) stations with esp8266audio librairy and an exemple of web radio.
I add a potentiometer to select station with analogRead and some code to copy ssid/password and stations in eeprom by UDP.
I begin with a esp8266 and because of memory i use now an esp32, more stable because not in limit of memory.
It works fine ,and i thank for this librairy . Just having two little problems.
1) On esp32 (not on esp8266) before changing url , i close mp3, buff and file the esp32 reply by UNINSTALL I2S and it takes 4 seconds to hear new station, not on esp8266. Is it possible to reduce this time on esp32.
2) On French public service stations (only) it cut the words, some milliseconds are missing in audio, theses stations are all on the same server and they are knowed to produce problem on some internet radio, not on all and not on PC or Android , i get an esp32 also to increase buffer size but the problem is the same. Is there a solution for theses radios ?
Here is the code of my radio (need a potentiometer on analog port , a button on port 14, a led on port 16)
If it is usefull, i can translate comments to English

// Sound quality is really good with the standard oversampling 32. And even better with oversampling 64.

Hello, I made a kitchen radio with 20 (soon 5 x 20) stations with esp8266audio librairy and an exemple of web radio. I add a potentiometer to select station with analogRead and some code to copy ssid/password and stations in eeprom by UDP. I begin with a esp8266 and because of memory i use now an esp32, more stable because not in limit of memory. It works fine ,and i thank for this librairy . Just having two little problems. 1) On esp32 (not on esp8266) before changing url , i close mp3, buff and file the esp32 reply by UNINSTALL I2S and it takes 4 seconds to hear new station, not on esp8266.

Is there a solution for theses radios ?
Two of French public service radio that have the problem http://direct.franceinter.fr/live/franceinter-lofi.mp3 http://direct.francemusique.fr/live/francemusique-lofi.mp3 same exist with midfi in place of lofi, same problem.
