Sequential concatentation to start before the previous sound has finished
Not really an issue but a requirement.
It would be useful if you were able to make a wav file from many wav files. But instead of sequentially waiting until one sound finished before concatenating it to the end, you can start a sound before the first finished. So really I'm looking for a mixture of parallel and sequential, but the sequential being able to be added at a specific time before the previous sound has finished. Is this possible? Could you do it?
Thanks.
What you want can be done by this. You just need to use parallel mixing with blank audio input.
Aren't wav files supported?
Thanks for getting back to me quickly,
You'll have to detail this as I've tried
audioMixer.addDataSource(input1); // 2 secs long audioMixer.addDataSource(blankInput); // 0.5 secs gap audioMixer.addDataSource(input2); // 2 secs long
audioMixer.setMixingType(AudioMixer.MixingType.PARALLEL);
The desired output would be to play at 0 secs input 1; then at 0.5 secs play input 2. (when input 1 is still playing)
The above is just putting everything in parallel so they all play at the same time.
If I change the setting to SEQUENTIAL then at 0 secs input 1 is played, then at 2 secs there is a gap at 2.5 secs input 2 is played.
Please explain how to achieve desired output.

Sorry, I gave the wrong answer. Currently this not possible with this. Need to do some work.
Thanks.
I look forward to it!

Hi Rakibul,
When will this be ready? I'd really like this functionality.

Your problem has been solved. You can now set startOffsetUs() to GeneralAudioInput. Use version v1.1
Do you have the previous version's code? I need the README.md file. Could you provide me with that, please?
Just did a quick rattle test and it's looking fantastic. So many thanks. It's looking like an excellent API.

Hi Rakibul, We are using the API in a proper project and it's become apparent we need some functionality adding. We have created about a 10second wav file and we intend to loop it using MediaPlayer setLooping(true) The issue is we don't want to wait until the loop has finished to start again. We want to start the next loop at a designated time before the previous loop has finished. Would this be possible? Thanks.

You want this while playing with Mediaplayer? I haven't got you properly.
Yes. Thanks to your API we have created a 15 second .wav file with lots of individual sounds running in parallel and sequentially. With the offSet functionality we have been able to mix sounds properly without having to wait until a previous sound has finished.
However we intend to loop this newly created 15 second .wav file. We are using MediaPlayer to play this .wav file.
Unfortunately, when trying to loop this new .wav file, you have to wait until the whole wav file has finished playing. Are you able to extend your functionality so that we can loop the wav file, without having to wait until the very end of the file. We need to able to start the new loop at a designated offset before the previous loop has finished.

You can add one audio multiple times. You can add the previous Audios again with new AudioInputs with your required settings. You have to calculate the startOffset for looping.
The issue with creating a huge wav file with AudioMixer (and not looping in MediaPlayer) is that it''s slow to create and the volume is really low.

Maybe i will have to do something to maintain the volume. I already have thought about it. Let me do something with volume. But i can't do anything with timing.
