Audio track preview in timeline?

Hello, loving the new timeline features.

Should I be able to hear an audio track when preview playing the sequence in edit mode? I created a totally default mixer/group and it works fine when I enter play mode, I just dont hear any sounds when pressing play in the timeline window. No console errors or any other glitches.

To add a twist, I'm using the older 5.6.0 beta timeline build, rather than the new 2017.1 timeline preview build. Is audible preview a feature in 2017 and not 5.6?

Many thanks,
-Jack

 

I just installed the 2017 beta and have the same "problem". The audio preview feature is absolutely necessary, please help.

 

Good to know that it really works like that. However, audio in preview mode is absolutely necessary.

 

Would be ideal to have audio in the Timeline preview window. Thanks

 

Hey! If I add audio clips in Play Mode I'm unable to hear them playing until I restart the Play Mode. Is it an intended behaviour as well?

Also is it planned to add the ability to change volume / pan / pitch of audio tracks? Right now I can, of course, add the the game object with the audio source component to the timeline and animate it's properties with record button on separate track. But it really feels like a workaround but not the solution.

Thank you for your time!

P.S. Plus one vote for hearing the audio playback in the Edit Mode.

 

If I mute audio track while in Play Mode it also doesn't do anything, the audio will play until I restart the Play Mode. It would be an underestimate to say it is inconvinient

 

I made a custom playable in order to solve that (doing a playable to show subtitles) but i cannot figure out how to adapt playable duration to AudioClip lenght.
Can someone help me?

 

Hey!

I met another problem. If I want to change a volume of the audio track, I'm adding the gameobject with audiosource as an animation track and animate it's volume. It works well. But when I try to change pitch of audio source, it doesn't affect the actual pitch of the track. I mean even with crazy pitch values like 0 or 100 there's no changes in the sound. Does anyone have a clue how to defeat this problem?

Thanks!

 

I was sort of shocked to find out that Timeline cannot play audio in the Editor and that Play Mode is required to hear the audio clips- Has anyone created a script or technique to get editor audio playback with Timeline? Thx

 

It would be great if the timeline preview played audio, but an (easier?) stop-gap feature would be to at least render the waveform in the timeline (maybe in a foldout, under the bar). You can synchronize a lot of edits to the waveform.

 

Happy to hear waveform is in 2017.2. Thanks!

 

I am syncing actions to a pre-recorded speech. One of the benefits of Timeline is the instant preview capacity, and if I can't hear the sound in the preview I cannot sync and co-ordinate the speech actions easily.

In my game a character is pre-recorded to say "Let me show you your magic wand <PAUSE> There you can see it by my right hand"

I need to coordinate showing the Wand Gameobject somewhere between wand and <PAUSE>. This would be easy to do if audio played in Preview and is currently frustrating to enter playmode to kinda half do it.

So I vote for audio in preview.

 

You can press play, then scrub the timeline!

 

Anyone know how to adjust audio volume using timeline?

 

I'm wondering about the same thing.
If you play your audio from a gameobject, you can't set speed of a sound (only pitch). That is a great timeline feature. But when you play audio from timeline, you can't set audio volume. It's annoying!

Great job, but unfortunately useless for me till it doesn't work with built app :/

 

I'm adding game object with audio source as animation track and animate volume with inline curves. Not super handy but does the job

 

Yea, I do the same now, it's ok.
I thought that the "Speed Multiplier" (which is a field in an audio track on a timeline) is something different than the "Pitch" (which is a field in an audio component attached to a gameobject). But I tested it, and "Speed" and "Pitch" do the same thing. The only difference is that the "Pitch" max value is 3, the "Speed" max value is what you want.

I think that the name "Speed Multiplier" can be misleading, because speed of a sound, and pitch of a sound, are different things. They are connected in some way, but in some audio program you can change them separately, like increase speed and keep old pitch. Which is great feature I think.
You can check this here:
https://www.coursera.org/learn/music-technology/lecture/fBhhp/changing-the-pitch-and-speed-of-sound

 

I agree, the pitch represents the height of the sound but the speed also affects it's length. Naming same thing with both words may be mesleading.

 

*sigh* And it seems audio once again gets the shaft.

Hopefully there are some improvments. The wave form thing is nice though, I'll give it that. ... Not a replacement though.

 

Thanks so much Ziboo. This was really helpful. You're great!

 

Hello,

Every so often, Audio in my timelines does not play. Audio outside the timeline (managed by scripts etc) still work fine. The only way to get the audio back is to restart unity.

Any ideas?

Thanks,
rich

 

I would also like to see Audio preview and scrubbing in the timeline window. That would make syncing things up a lot easier for sure. Rubber-band style volume/pan editing tools (used in typical DAWs) would also be great for mixing the audio volume levels.

 

I have the same problem

 

Is there any Update regarding the bug of the audiotrack still playing even though Playmode is paused? I searched for #930268 in the Issuetracker but could not find any entry. Using 2017.1.0p5 atm and have not found any mention of audio/timeline-related stuff to this bug in the 2017.1-Patchnotes.

 

+1 on audio scrubbing in timeline. Really important.
Jeff

 

Bump audio track playback in preview only (not play).

 

Any ETA on this? Where on the roadmap does it fall? Our artists came from Flash, and it was much easier for them to make sequences that need to be aligned properly to audio when they could scrub back and forth. I built this in myself, but its a bit buggy and definitely not as good as you guys taking the time to actually handle it properly. I figure though, that if I could get something sorta working without a tremendous investment, you guys should be able to figure it out (no offense meant, I mean that sincerely). If its purely you don't think its a pressing issue ... it is, at least for whatever demographic we fall under.

I just wanted to say thank you for this. It works great and is helping a lot while working on a trailer using Timeline

 

keijiro has like 99% of the good repos for unity on github. The mans a legend.

 

without this, professional quality lipsync can't really be animated in unity....

 

When i insert my game object, that has an audio source component, into a track in my timeline, i should be able to control all sound in that audio track using the controls in the audio source component on the game object. Correct? But when i change the volume or anything on the component of the game object, it doesn't make any changes to the audio that is in my timeline. In my specific case i have some music that i have in a track in my timeline. So i made an object with an audio source and connected it's audio source to the timeline track. However, the changes to the audio source component do not affect the track at all! I turn down my volume to 0 and still could hear it playing. Am i just super confused here? What is going on? What did i miss?

 

I'm having this same exact issue!

 

Hi. Got a bit of a new situation here with 2018.2. I'm using the Timeline Playable Wizard to recreate the AudioTrack with additional properties (as I can't get my hands on the original script).
Track binding type: audio Source
Behaviour variable: audioClip
But even with those, the clip waveform doesn't appear & scrubbing/preview functionality doesn't work (whereas it works with audiotrack ) Any idea to help? Thanks

 

Is there a way to change the behavior of how the audio is scrubbed?

The current implementation seems to play back audio by adjusting the audio's pitch in relation to the speed you scrub. This is great! Although, because the playback pitch is very low when you scrub slowly, it is at times very difficult to hear. It makes certain tasks difficult, such as lip-syncing, or other tasks that require very fine adjustments.

A solution that I'd find really useful is to not change the audio's pitch, but play back small samples at the native pitch as you scrub. I'm not sure how else to describe this. It would be wonderful to have both scrub behaviors. Here's a video of someone displaying this scrub style in After Effects:

Is this feature already available? And if not, where's an appropriate place to make a feature request? I thought this might be a good place to start. Thanks!

 

So, I'm using Keijiro's audio preview version for now, I've discovered it has the exact functionality I need. It plays one frames worth of audio at native speed as your playhead enters a new frame, or something to that effect.
This type of scrubbing is very important for precise manual work, like lip-syncing, which is what I've been using Timeline for lately. Please consider including this feature as an option in future builds.

 

Keijiro's audio preview track repo readme now says:

 

Hi @Leuthil , thanks for the response. Yeah, I'm aware of the repo readme.

The two implementations – Keijiro's and official 2018.2 version – handle audio playback differently. My point is that Keijiro's audio scrubbing implementation is more useful to me than the official 2018.2 implementation. I believe Keijiro's implementation will be considered more useful to most people who are syncing clips to audio tracks with precision down to a single frame. (I explain the difference in audio playback a bit in both of my posts #46 and #47).

I would like to see the official implementation extended to provide an optional audio playback behavior that is similar to Keijiro's version, or the After Effects implementation. (I included a link to video example of the after effects implementation in post #46).

 

Ah I see. Sorry I thought your post was before 2018.2.
