WAAPI getter for sound prefetch size

Question

Hello,

The same way there are multiple sound-only properties getter available in WAAPI, would it be possible to expose an audio source prefetch size?

Thanks!

Answer 1

Prefetch Size

The prefetch size (bytes) in the converted file is not accessible with WAAPI.

You can access the value in the SoundBankInfo files (json/xml), generated with the Soundbank files:

    "IncludedMemoryFiles": [
     {
      "Id": "230377263",
      "Language": "SFX",
      "ShortName": "2_blocks.wav",
      "Path": "SFX\\2_blocks_D79FB2B7.wem",
      "PrefetchSize": "9664"
     }

We also plan on adding WAAPI a topic you can register to be notified when SoundBanks are generated, containing the prefetch size:

Prefetch Lenght

The prefetch lenght is accessible directly as a property on the Sound objects, see here:
https://www.audiokinetic.com/library/edge/?source=SDK&id=wwiseobject__sound.html

PreFetchLength: Prefetch length (ms)

To access the value, use ak.wwise.core.object.get on Sound objects, with "@PreFetchLength" in the return options:

Comments

Hello Bernard, thank you for your answer.

However I'm looking specifically for the prefetch size in bytes once encoded - as it might change depending on the conversion being applied etc.

Do you think this would be possible?
