DFPlayer latency
cavimaster 2016-01-08 14:55:20 9817 Views5 Replies Hi everybody! Is my first post
I am the happy owner of a DFPlayer and I find this incredible module. We can do whatever we want almost.
In my application I need quickly trigger sounds in rhythm and without latency or so with a very low lantence.
Currently my Arduino code is well, everything works except this latance at least every 100ms trigger sounds while my goods are cut early.
I tested directly on the module without trig passser by the Arduino board and I have the same playback delay.
A genius idea to reduce this latency? or perhaps information on specifications for I have not found...
Thank you very much for your help and my apologies for my "google" English

2016-02-19 19:25:00 Hi cavimaster,
Ok, I thought that was because the delay(10) causing the latency of your command. So it should be the chip that it has a low speed of respond. Oh, I came to think about if you have placed too much music files in your TF card? Too much folder or too much files will make the chip harder to find the target file~~ Leff

Thank you for helping xxLeff but that make no effect.
My pbm is that when the trigger high sounds be play directly and is not the case. The 10ms become after the play cmd.
In fact, in addition to the delay the begin of sound is "eaten". I have to go to the evidence: this module is not make for this

Maybe you could delete the delay() in the library to decrease the latency to have a quick responce if there is.

Our engineers are investigating the latency issue to see if we can improve it. If we find anything we will post in this thread. Maht

Il look to the direct flash reading side but i dont know who to do. cavimaster
