Request for Adding Delay Between Tracks in Flutter Just_Audio Playlist

[burhanaksendir]

Is your feature request related to a problem? Please describe.
I am experiencing issues with sound transitions when playing a playlist with podcast content. Specifically, there is no gap at the beginning of each track, causing audio problems when transitioning to the next track.

Describe the solution you'd like
I would like to be able to add a slight delay at the beginning of each track in a playlist when using the flutter just_audio package. This delay would help prevent audio issues during transitions between tracks.

Describe alternatives you've considered
I have considered manually editing the audio files to include a brief silence at the beginning of each track. However, I believe having a built-in feature within the flutter just_audio package to handle this delay would be a more efficient and convenient solution.

Additional context
I have a playlist containing podcast content, and the absence of a gap at the beginning of each track leads to audio problems when transitioning between tracks. To address this issue, I am seeking a way to introduce a delay during the transition between tracks to ensure smoother audio playback.

Thank you for the suggestion, although I feel this feature would be a little to niche, and unnecessary since there are alternative approaches.

You could also create an audio asset containing a short amount of silence of the desired length, then use a concatenating audio source to concatenate it before each item. Those silent assets will be indexed in the player's sequence, so you probably won't want to use the player's sequence directly as the model for your UI. You would need to then manage it yourself which is a downside, but it is at least possible.

This is similar to other requests to support crossfade transitions and such. These are all possible to achieve without building it directly into just_audio, but just require more effort on the part of the app developer using the library.

Thank you for your response and providing alternative approaches. Would it be more practical to add a delay when transitioning to the next track in the playlist? Is it possible for you to provide a small code example demonstrating how to achieve this?

Can you be more precise? If by delay, you mean Future.delay, then no because that could potentially relinquish control to the os when in background mode on iOS.

I appreciate your clarification regarding the potential issues with using Future.delay. To be more precise, yes, I was referring to Future.delay, and it seems that I've encountered challenges in finding a suitable solution for the mentioned issue.

Additionally, I'd like to highlight that the playlist contains hundreds of podcast episodes, and individually managing each one would be time-consuming. Therefore, I'm actively seeking a more efficient and streamlined method for this task.

I'm still exploring options to find a more seamless and efficient way to introduce delays between podcast episodes without compromising the user experience. If you have any further insights or alternative ideas, I'd be grateful for your input.

I would suggest a silent asset as mentioned above. I can't think of any further comments or insights to add on top of that. A variation of simply inserting the asset into the ConcatenatingAudioSource before each podcast episode would be to dynamically generate an HLS stream representing one episode and insert the silent asset as the first file in that HLS stream, and produce one HLS for each episode. I'm not able to advise you in detail on how to do that, however. You can research the two alternatives and weigh up their respective advantages and disadvantages.

I added SilenceAudioSource between each episode but it sabotaged the indexing, did you find any other solution?

[ryanheise]

If you customise it like that, you will need to also manage your own indexing, i.e. keep your own variables to track the current index in your app's own frame of reference and so on. I think I have answered similar questions on stack overflow before.

player.positionStream.listen((position) async {
if (position == player.duration) {
player.pause();
await Future.delayed(Duration(seconds: delayFactor)); /// 5-second delay for example
player.seekToNext();
player.play();
}
});

  This's the finest answer i could get, although it's not the best solution but should work!
