WAV Export Support for Stems

Description: Many users would like the ability to export stems in WAV format instead of MP3 only. Currently, stems are delivered as compressed MP3 files, which can limit flexibility for: Professional mixing/mastering DAW workflows Studio production Audio quality preservation during editing Re-recording and post-processing Requested improvements: WAV export for individual stems WAV export for full stem bundles Optional selectable export quality/formats (MP3, WAV, FLAC, etc.) This would make Stems Studio much more useful for musicians, producers, and advanced creators working in professional audio environments.
