This has the advantage of no reading time from the storage medium and small memory usage with the tradeoff of using a little bit more CPU to decompress and decode every time it is played. Compressed in Memory will store the audio data in its compressed state in the memory, but will require CPU to decompress and decode when it’s played.The trade-off to this is that the audio data will take up the maximum amount of space in the memory, and that’s why it’s only suitable for small audio files that are played very often and need to be ready in a very short time, like footsteps, UI sounds, gunshots and other weapon sounds, etc… Decompress on Load will decompress and decode the audio data into the memory to its original size, making it ready to play on-demand with the least amount of CPU usage.Let’s summarize what we’ve learned so far: The original audio asset was 26.8 MB and was compressed with Vorbis for a final size of 3.4 MB Final Words This compromise between RAM and CPU makes Compressed In Memory a good setting for audio files that are played back somewhat often, but not often enough to need them constantly ready in a decompressed and decoded state, such as object interaction sounds.

Contrary to some information we’ve found online, once played back the audio will stay compressed and will need CPU to decompress and decode every time the audio is called. SummaryĬompressed In Memory gives us the advantage of the lightning-fast read access from RAM, but will require CPU power every time the sound is played back. Unity has a small overhead on storing compressed audio files in the memory, making it always a tiny bit bigger than its compressed size in the storage medium.Īs soon as we play the audio data, it will first be decompressed and decoded, a process that requires CPU resources as the audio data is playing. Less space required in memory, but we needed more CPU for playback.Īs expected, the audio data is loaded into the memory in its compressed size. That means: to be able to create an audio signal that a playback device actually understands, it needs to be converted to PCM.

The decoder will most likely be integrated into the software or, in some rare cases, you will have actual hardware or a chip taking over the decoding process to relieve your CPU. Most audio devices are waiting for PCM data. Usually, an application that plays encoded files (be it audio or video) will need to decode that file to a format that the target device can output on a standard port. This may seem like a contradiction, but if you’ve read through our last post you know that PCM’s advantage is the very low to almost non-existent CPU usage needed for playback. GameObject.Where and when audio is decompressed and decoded depends on the Load Type Why is PCM Always the Final Format?Īt this point, you might be wondering why all of the audio data we’ve stored so carefully as Vorbis, ADPCM, or other compressed formats need to be decompressed and decoded to the PCM format.

How I make my music continuous: void Awake() I thought it's a component, not an object! Might be both, I'm not sure. "The object of type 'AudioSource' has been destroyed."Ĭan anybody help? Also. For some reason, it works just fine UNTIL the game reloads/changes scene. I have audio in background (that plays throughout the whole game, even when the scene changes), so I've decided to make the music stop while the game is paused.

I just introduced a pause option to my little testing game.
