Large Files and Memory

An audio file's disk size and its decoded memory usage are different. Compressed and lossless audio of the same duration may need similar memory when decoded to the same sample rate and channel count.

Import Limit Exceeded

The current general import limit is 30 minutes, tightened according to the device's decoding memory budget. When exceeded, follow the prompt to select the section you need before importing.

A single audio file over 1 GiB is rejected; split it or reduce its size first. Video follows its own processing path, so the audio size rule cannot be applied directly to it.

Browsers lack the app's native media editing. If large-file processing limits are reached, trim in the app or another editor before importing.

What Compression Can Solve

Compression mainly reduces media storage and transfer size and may change audio quality. It does not guarantee less decoding memory or bypass duration limits.

If practicing only a few minutes of a recording, trimming the required range is more direct. Shorter audio reduces the material that decoding, waveform analysis, and separation must process.

Instrument Separation Limits

The current single-separation duration limit is 15 minutes, with model and device memory requirements too. If requirements are not met, try the Standard model, trim the media, or close other memory-heavy apps.

Even when the interface lets you try, insufficient system memory may cause failure or exit. Save the project first, then follow the device prompts.

Video and Cache

If only practicing audio, remove video to reduce storage. Files generated by playlist Power Saving Mode are regenerable cache. Clear them in Settings without deleting project media.

Does Trimming Reduce Audio Quality?

It depends on the codec and processing method. Some AAC/ALAC audio can be remuxed directly; other formats may be re-encoded to AAC. Do not assume all trimming is lossless. Back up first if you need the original media.
