Muffled audio export (Animate > Media Encoder)

[ÉCLAIRAGE PUBLIC]

Hello everyone,

I am working on animations from 9 to 18 seconds.

And I am having problems with the sound output on the 18 second formats where the music seems muffled.

While it is perfect on the 8 second formats.

The sound at the source is perfect, when editing on Adobe Animate too, it is only when I export with media encoder that the sound is degraded.

However I use the same encoding parameters on the 8 seconds as on the 16 seconds!!!

Audio input :

Rate : 44,1 kHz

Bits  : 16

Media encoder parameters :

- Preset used: Match Source – High Bitrate

- Video: 2160x3840 (1.0), 30fps, Progressive, 203 (75% HLG, 58% PQ), Hardware Encoded, 00:00:18:03

- Audio: AAC, 320 Kbps, 48 ​​kHz, Stereo

- Bitrate: VBR, 1 pass, Target 10.00 Mbps

Thanks for your lights because there... I am in the dark...!

change the output parameters to match the input

Thanks for your answer.

Do you mean that I have to change the parameters in Media Encoder to match 44,1 kHz and 16 bits ?

[kglad]

try it.

Well... I tried with this configuration but it doesn't change anything...

What I don't understand is that in my 8 second animation, after exporting in media encoder, the sound is perfect while in the 16 second one the sound is muffled. But both have a source audio file in WAV 44.1 kHz 16 bits...

I found the answer!

Actually I was working in Canvas mode. For those who will have this problem in the future, here is what to do:
File menu > Convert to format > Action Script 3.0.
Then File menu > Export > Export a video
And that's it, nothing else to do, it works! 🙂
