Extract `Himel Audio.zip`. 2. Use the session folders as the primary organization unit. 3. Review the nested `Walid.zip` package if you need the complete session 3 content. ## Notes - The archive is organized by recording session rather than by train/validation/test splits. - File naming is mixed across sessions, so keep the original folder structure intact when copying or extracting.
