Dealing with large audio files

[AudioFan]

I have a large mp3 file that I have tried to load which loads into the waveform as long as I have the resolution set to minimum, not a big problem but the problem lies when trying to do anything with the file in terms of applying say flat volume or inserting silence or other effects.
The waveform will not reload showing the editing change, and regardless of what I set the display at the file is no longer available.
I tried it with the sound editor sample and it has the same problem.
Are they file size limits?

Thanks

Hello.

Have you tried to set the "store mode" of the control to STORE_MODE_TEMP_FILE through the SetStoreMode method before loading the file?
When dealing with large files this is highly suggested because, due to the usual Windows memory fragmentation, the PC could not have enough contiguous memory to perform editing sessions.

That seems to work but a I am sure you know quite a bit slower.
Is there a recommendation as to store mode to memory size. Such as if someone has 2gb of memory what is the largest file size that makes sense for memory?

Thanks

Hello.

As specified inside the section of the documentation "How to use the control in your projects", it's strongly suggested avoiding memory based storage for clips longer than 10 minutes: it's quite obvious that disk storage is a bit more slow respect to memory storage but, as mentioned, memory fragmentation is something to keep count of.
