I have the music that is always run in the background and some activities that would play sound when triggered. The music works fine.
pygame.mixer.music.load(os.path.join(SOUND_FOLDER, 'WateryGrave.ogg'))
The problem I have is that when there are 2 or more activities triggering sounds, then only one would be played (not including the background music) and the rest are muted. Is there any solution to this?
you can add sounds to different channels using the mixer:
pygame.mixer.Channel(0).play(pygame.mixer.Sound('sound\gun_fire.wav'))
pygame.mixer.Channel(1).play(pygame.mixer.Sound('sound\enemy_hit.wav'))
Within each channel you can still only play one sound at a time, but you can group sounds into different channels if they would need to play at the same time.
You can add more channels like this:
pygame.mixer.set_num_channels(10) # default is 8
A simple example. For the docs on Channels, go to:

I am having so much trouble doing something that should be SIMPLE. I do sales for a golf course and I have to read the same thing over and over again on every call and it gets so damn annoying. I want to be able to play a pre-recorded wave/mp3 file through the mic input of my headset so I can just play the recording at the right point in the sales cycle instead of repeating it 200X a day. I have succeeded in doing it with stereo mix BUT it will disable the voice aspect of the microphone so when the recording is finished, I have to jump into setting real fast and switch the mic input - which is not doable.
I know there is a way to do this. I see twitch streamers do this sort of thing all the time. I have tried SO MANY methods and nothing seems to work.
I'm working on a WinRT project in which I'm playing multiple video files at the same time. I have 3 audio devices attached to machine which will be used distinctively to render audio from video file(s) that's playing. Maximum number of videos that can be played simultaneously is 3. Hence each audio device would be used to render audio from its corresponding video file. i.e. Audio device 1 would play video 1 and so on. That's the requirement I have.
So far, I came across two approaches. First, we use Dolby or any other API to channelize audio to corresponding device. i.e. left channel is rendered to device 1, middle/center to device 2, and right to device 3. I've tried Dolby Audio sample app for Windows 10. They've done channeling in embedded video, not in code. I couldn't find documentation for Windows 10 Dolby API. So for this approach, can I render audio in form of a channel to a particular audio device? And I don't want to merge audio in anyway.
Second, we use 3 sound cards and attach an audio device to each one. We choose the device we want to play audio on by providing device ID. I've tried this approach with XAudio2 by calling createMasteringVoice() method with device ID I want. That worked for single audio file, however, I want to render audio of multiple videos that are being played.
Both approaches didn't solve the core requirement yet. So considering the scenario, what is best approach to follow to fulfill the requirement?
I would say you can go with XAudio2 as you mentioned in second approach. Since you can pass deviceId to createMasteringVoice(), you can create multiple instance of UniversalAudioPlayer and pass different IDs to each one. This way multiple sounds can be played concurrently. Take a look at function definition and community additions here.
I want to create a game with sound effects. When I start the game, the background music should be played until the game is over. When I click on something in the game (such as buttons), a sound effect should be played but the background music is stopped.
How can I make the background music play continuously while the sound effect from object is playing?
I already have these scripts...
Card script...
on openCard
play "backgroundmusic.wav" looping
end openCard
Buttons (or any object)...
on mouseup
play "sound.wav"
end mouseup
How to play these sounds together?
Update: I found a game uploaded to Game Jam. This game was ranked #1. When I play the game, the sound was amazing that it has background music and sound effects. But the owner of this game doesn't upload the livecode stack file in order to study it. The game was entitled Space Shooter Game. The sounds of this game is what I expect.
Note:
As what I figured out from the answers, using the player object can be work. But this requires QuickTime which I don't have that installed in my PC. I want also the sound to be able to play in mobile devices.
As it stands, the soundChannel property has no effect in LiveCode and is only provided for Hypercard compatibility.
Currently on desktop there are two ways to do multi-channel sound: 1) play imported sounds as one channel, and use a player object as the second channel, or 2) use two player objects.
Typically, a good option is to import short sounds as sound effects into a stack that only play once, and reserve the player object for background music. Imported sounds usually play with the least latency, however, you cannot play multiple imported simultaneously -- attempting to play a second sound while a first is playing will stop the first to play the second. If you have a need to play asynchronous sound effects, this option will not work; you must use a combination of playback options.
Multiple players can be used, but note that there can be some latency during the process of loading a sound (assigning a sound's filepath to a player) and playing it.
Also note that truly seamless playback of of a track is difficult if not impossible -- LiveCode will at some point become susceptible to some system event that will cause a slight pause between loops. A while back, Trevor Devore made an addition to his Enhanced QuickTime external that enabled true seamless looping of audio. However, with Apple getting rid QuickTime, it's unknown how much longer this option will be useful.
With the enhancements that the RunRev guys have been making to the engine, it's likely we'll see improvement with media playback and management, hopefully sooner rather than later.
In the LiveCode forums, they suggest using player objects on the card instead and telling them to play.
In HyperCard, you could set the soundChannel property for that. Have you checked in the LiveCode documentation whether it supports that? The docs for the play command and the the sound property might also help. Maybe those contain hints. FWIW, in HC
set the soundChannel to 1
play "BackgroundMusic"
set the soundChannel to 2
play "SoundEffect"
would play the sound effect and background music at the same time. Maybe that's how it works in LiveCode as well?
The multimedia capabilities are a going through a transformation. Previously everything was built around QuickTime (well almost everything) and you needed to add a player control for each concurrent sound. Currently the whole foundation is changed as Apple dropped QuickTime, but assuming you develop for desktop you should still (again) be able to add a player object and then use:
start player "name of player"
You can also create player object dynamically by
create player "my player""
and then use
set the filename of player "my player to "/path/to/your/audio/file"
before staring your sound. And as long as you have different players for your different sounds they should play simultaneously.
on openCard
put specialFolderPath("engine") & "/soundfx/backgroundmusic.wav" into tSound
mobilePlaySoundOnChannel tSound, "Background", "looping"
end openCard
on mouseup
play "sound.wav"
end mouseup
Is there a difference between audio.play() and media.play() and which one is better?
The audio.* API calls use the OpenAL audio layer to play. They are considered a safer and better way to play audio in Corona SDK. You can have 32 different sounds playing at once. You can control the volume on each channel independently, pause and resume, fade in, fade out, etc. It is the preferred way to play sound.
The media.* API calls write directly to the hardware and you cannot control the volume, have multiple sounds going on. The media.* API Calls though are good for video, playing long clips, like podcasts since that audio can be backgrounded, but more importantly, on Android, Google has decided to poorly implement OpenAL and under 4.x there is a significant lag from the time you tell audio.play() to play a sound and it really happening. The lag isn't as bad under 2.2 and 2.3, but there still is a lag. The media.* api calls, if you're playing a short clip will play in a timely fashion.
media API:Only one sound can be playing using this sound API. Calling this API with a different sound file will stop the existing sound and play the new sound.
Want a player (easy enough to put up) that plays back a directory of mp3s in such a way that if you join at 3:33:33 pm, you hear what others hear, not track one. like a pseudo broadcast/stream. how do i achieve that - what looks nice / is probably minimizable / is easy?
i am trying to use mirvling but no such luck. any ideas?
It's unlikely you're going to find something to drop in place. Plus, this isn't typically handled on the client side of things. You neglected to specify what languages and what not that you are using, so I'll provide a general answer.
There are two methods to accomplish this.
Method 1: Encode the stream on the server
Basically with this, you create an audio stream on the server that is made up of the audio files being played back. The clients play an audio stream like any traditional "live" internet radio station, without knowledge of how the stream was created. You can use SHOUTcast/Icecast for the servers, and a number of different source stream encoders, such as Ices.
Method 2: Make the media available and let the clients figure it out
For this, you'll be starting from scratch. Have a JSON feed or similar served up that contains a playlist of the audio files that should be played and when. On the client side, you can use JWPlayer or similar, and seek to the desired position of the current track when it starts, and then play tracks in order from there.
