Scratchy Bluetooth audio output

[AydySmith]

I got my speaker working nicely using a Bluetooth input and writing it to an I2S Stream, there were no issues with the playback. So I decided to start adding filters (As directed in the documentation) and the audio has become scratchy (for lack of a better word). it almost sounds like there is a very small delay between bits being output and this makes the music almost bounce if that makes sense. I'm not too sure what I am doing wrong.

I first define what I need for the filter(using the values from the docs as I have no frame of reference yet):
FilteredStream<int16_t, float> filtered(i2s, channels); StreamCopy copier(i2s, filtered); float coef[] = {0.021, 0.096, 0.146, 0.096, 0.021};

Then I call this filter in setup:
filtered.setFilter(0, new FIR<float>(coef)); filtered.setFilter(1, new FIR<float>(coef));

I haven't really used this functionality. I suggest that you have a look at ESP32 Arduino with arduino audio tools - Using Filters from NA5Y and that you use https://fiiir.com/ to determine your parameters

Thank you, I took a look at the video, and it will be of help down the line. I have played around with the code to try to get things working and now the ESP32 is just continuously rebooting:

rst:0x3 (SW_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT) configsip: 0, SPIWP:0xee clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00 mode:DIO, clock div:2 load:0x3fff0030,len:1284 load:0x40078000,len:12808 load:0x40080400,len:3032 entry 0x400805e4 ets Jun 8 2016 00:22:57

So I need to figure that out first, then I can get back to the filters. My best guess is that it's something to do with the A2DPStream class because there hasn't been an issue when using I2SStream with a2dp_sink, so I might have to move back to that.
