## Description

Watch and hear 32 classic sorting algorithms in action. Every comparison rings a note; every pass paints a pattern. Six sorts free - unlock the rest for $1.99.

Sound of Sorting visualizes 32 classic sorting algorithms with live audio and motion. Every comparison rings a note; every swap redraws a bar. Watch - and listen to - how each algorithm pulls an array from chaos into order.

Originally released in 2013 as a C++ demo for university algorithms classes, Sound of Sorting has been viewed tens of millions of times on YouTube. This is the app version: native, fast, and rebuilt for touch and trackpad.

WHAT YOU GET

• 32 sorting algorithms, from familiar (Bubble, Selection, Insertion) to obscure (Cycle Sort, Smooth Sort, Block Merge Sort)
• Real-time audio: every array access plays a tone whose pitch matches the value being read
• Colored bars: access highlights, permanent marks, sorted regions — all in live animation
• Adjustable array size (8 to 2048 elements) and animation speed
• Step mode: advance one comparison at a time
• Infinite Play: start a never-ending parade of random sorts
• Live stats: comparison count and access count update as the sort runs

FREE ALGORITHMS

Six foundational sorts included at no cost:
• Selection Sort
• Insertion Sort
• Binary Insertion Sort
• Merge Sort (classical recursive)
• Merge Sort (iterative)
• Quick Sort - Hoare (LR ptrs)

FULL COLLECTION — ONE-TIME PURCHASE

Unlock the remaining 26 algorithms with a single $1.99 purchase:
• More Quick Sorts - Lomuto (LL ptrs), ternary (LR ptrs, LL ptrs) and Dual-Pivot partition schemes
• Bubble Sort, Cocktail Shaker Sort, Gnome Sort
• Comb Sort
• Shell Sort (Ciura gap sequences)
• Heap Sort with heap level coloring
• Smooth Sort
• Odd-Even Sort, Bitonic Sort, Batcher's Odd-Even Merge Sort
• Cycle Sort
• Radix Sort - LSD and MSD variants
• gcc's std::sort and std::stable_sort - the real implementations
• Tim Sort
• Block Merge Sort
• Bogo Sort, Bozo Sort and Stooge Sort, for entertainment
• ... and more

No subscription. No ads. No analytics. No account. Just algorithms.

WHO IT'S FOR

• CS students learning how sorts actually compare in practice
• Instructors looking for a lecture demo that's easier to launch than running g++ live
• Engineers who want to rewatch a Quick Sort partition and finally see why it's fast
• Anyone who finds audio-visual algorithm traces calming to watch

TECHNICAL NOTES

Sound of Sorting runs entirely on-device. It makes no network calls, collects no data, and has no accounts. In-app purchases are processed by Apple.
