AAC VBR stream quality drops after a few seconds #506
Comments

No problem here. But I used the V2 version of the radio. |
|
sorry, Ed, copy & paste put in some HTML coding, this should be better: I tested the station frontend.streamonkey.net/radioc-live with Winamp and saw the bitrate varying from less than 50kbps to more than 150 kbps. I could not hear any loss in quality. Rainer |

Just tested with V2 and I2S output: no problem. |

-->Hello Ed, I meant the bitrate displayed using the test button on the web interface. I do not see this as an issue and there is no need for a change. Maybe an indicator that the data comes from a VBR station can avoid such irritations?I remember a similar issue (#476?) was reported some time ago which also came from a VBR station.

This is only displayed in the web interface for test purposes. It is the bitrate averaged over 10 seconds. Not intended to give a precise real-time measurement.—Reply to this email directly, view it on GitHub, or unsubscribe.You are receiving this because you commented.Message ID: ***@***.***>

Hello Ed, |
|
Why don't you install PlatformIO in 5 minutes? That saves some time ;) |
|
Haha yes, install was fast, but for me getting used to, took a bit more time. ;) I modified your code just for testing (should I fork this?). I made a similar function as the Timer10sec function called Timer2sec, but executed every two seconds to calculate the bitrate and print it via "mbitreq=true" to the serial monitor. Is it possible, that the streamonkey link has multiple streams with different bitrates and the ESP32radio switches (or is forced) to a lower bitrate? I really have no knowledge about such things.
Greetings, Stefan |
Hello,
I have this problem with this station:
frontend.streamonkey.net/radioc-liveWhen the stream starts, everything sounds fine, but after 15-20 seconds the sound quality drops and stays that way. It sounds like a really low bitrate.
When I switch to another station and then back, it sounds fine again for 15-20 seconds and then quality drops again.
The serial monitor doesn't show anything special:
