V3.4.4

V3.4.4
allow FLAC 24 bits per sample
and WAV 24 and 32 bps

V3.4.3

The output sample rate is no longer fixed, but depends on the audio source. If the DAC requires 48 kHz, this can be activated in Audio.h (#define SR_48K).

All decoders are now classes.

If there is more than one embedded image in a FLAC file, it is now output correctly.
e.g.
CoverImage: segment 00, pos 00000224, len 00007308
CoverImage: segment 01, pos 00007536, len 00005873

Streams are played back correctly even if the FLAC frame is larger than the OGG frame, http://amp.cesnet.cz:8000/cro-jazz.flac

char* null pointers are intercepted to prevent a crash.

If an ID3 header is unexpectedly sent during a chunked HLS aac stream, it is recognised and skipped, https://dd782ed59e2a4e86aabf6fc508674b59.msvdn.net/live/S97044836/tbbP8T1ZRPBL/playlist_audio.m3u8

Several issues with "chunked data transfer" have been resolved.
fix compiler warnings -Warray-bounds= and no trivial copy-assignment

V3.4.2

new event management
used "functional callbacks" instead "weak" compiler bindings

old

void audio_info(const char *info){
    Serial.print("info        "); Serial.println(info);
}
void audio_id3data(const char *info){  //id3 metadata
    Serial.print("id3data     ");Serial.println(info);
}
...
...

new

void my_audio_info(Audio::msg_t m) {
    Serial.printf("%s: %s\n", m.s, m.msg);
}

void setup() {
    Audio::audio_info_callback = my_audio_info;
    ...
    ...
}

V3.4.1

http range request ist enabled
This allows the jump within a file if the server accepts ranges

3.4.0

OPUS-HYBRID-MODE activated
C unique pointer introduced
better sync. lyrics

3.3.2

OPUS Hybrid Mode is activated, stations such as
https://st01.sslstream.dlf.de/dlf/01/low/opus/stream.opus?aggregator=web
work now,

The mode is displayed as info: (CELT_ONLY, SILK_ONLY, HYBRID)

Memory leak in VORBIS decoder fixed

Better 48KHz I2S output through cubic interpolation (Catmull-Rom)

ESP32-P4 support

Adruino Version > V3.0.0
PSRAM must be activated
The I2S signal is resampled to 48 KHz stereo 16bps

last release without PSRAM

The appropriate ESP32-Arduino version is 3.2.1.

V3.2.0

ESP32-P4 ready

3.1.0

Only supports Arduino versions from V3 and therefore no longer supports an internal DAC
