01 · You Drop & Collect

• Drag and drop individual files or complete folders
• Accepts XPM, WAV, MP3, M4A, AIF and AIFF
• Add more files to the same drop zone before processing
• Recognizes mixed folders containing audio and XPM files
• Shows files plus separate Drum Kit, Loop, Sound and Preset estimates before starting
• Leaves every original source file untouched

02 · It Reads & Resolves

• Inspects formats, filenames and surrounding folder context
• Follows sample references stored inside XPM files
• Uses nearby audio as source material for referenced programs
• Distinguishes drum programs, sample-based presets and plugin presets
• Separates loose samples from program-owned audio to prevent double imports

03 · It Converts Audio

• Converts MP3, M4A, AIF and AIFF automatically
• Reads WAV files containing 32-bit float audio
• Creates canonical 44.1 kHz / 16-bit PCM WAV files
• Preserves channel count and musical duration
• Prevents accidental silence from being added at the end
• Keeps the complete pipeline predictable across mixed formats

04 · It Listens & Classifies

• Combines filename clues with waveform analysis
• Recognizes kick, snare, hi-hat, percussion and bass
• Recognizes melody, synth, sample and rhythmic loops
• Separates detected loops into their own playable loop projects
• Detects tonal information where the audio is reliable enough
• Gives ambiguous sounds a safe Other destination instead of inventing certainty

05 · It Cleans & Balances

• Normalizes loose generated WAV files to approximately −1 dBFS
• Normalizes an entire preset with one shared gain
• Preserves relative levels between preset key zones and velocity layers
• Uses decoded-audio fingerprints to reject true content duplicates
• Checks file metadata first to keep large libraries responsive

06 · It Names & Numbers

• Uses clear category names such as Kick 0001.wav
• Continues numbering automatically beyond four digits when required
• Never overwrites an existing accepted sample
• Names drum projects with two English words plus “Kit”
• Names loop projects with two English words plus “Loops”
• Names Melody/Other projects with two English words plus “Sounds”
• Always combines peaceful words from two different categories

• Creates one reusable categorized SAMPLES system
• Keeps loops organized in SAMPLES/Loops while also building playable loop kits
• Stores native MPC Sample kits clearly in MPC SAMPLE KITS
• Keeps portable MPC programs and presets clearly separated

08 · It Remembers & Maintains

• Gives every SAUCE library its own persistent identity
• Shows when a valid library is ready on Mac, MPC or MPC Sample
• Creates a playable result immediately, even from only a few sounds
• Remembers one open Kit, Loops and Sounds project independently
• Fills the matching project’s free pads first during the next import
• Keeps every existing pad position and project name stable while it grows
• Closes a project at 16 sounds and then starts the next one automatically
• Safely adds missing files across known online libraries without overwriting or synchronizing deletions

16 · It Shows the Work

• Shows calm, real pipeline phases instead of technical log noise
• Displays live file and completed-output counts
• Uses measured progress rather than a decorative timer
• Allows safe two-click cancellation with rollback
• Accepts additional drops before processing begins
• Uses clear ready, processing and completion states

17 · It Runs as a Mac App

• Standalone macOS app named Sauce
• No subscription and no account required
• Custom Sauce interface and app icon
• Optimized for Apple Silicon Macs
• Requires macOS 13 or later
• Can be shared as a self-contained ZIP file
