Audio toolkit for solo game devs

Best for: classic 8-bit / chiptune SFX. Click the preset button (Jump, Pickup, Explosion, Hit), randomize until you like it, export as WAV. Zero learning curve.

Best for: sfxr's bigger sibling — more parameters, more presets, better for tuning a specific sound. Browser version + downloadable Flash app.

Best for: a step up from sfxr/bfxr — more synthesis options, including FM and LFO. Worth it if your game has more than four SFX and you need them to sound coherent.

Best for: recorded SFX (footsteps, doors, ambience) you can't easily synthesize. Massive library. Filter by license: stick to CC0 if you don't want to track attribution.

Best for: high-quality recorded SFX, especially ambience and Foley. Free tier requires attribution; paid tier removes it. Quality is well above Freesound's average.

Best for: the canonical free music library. Hundreds of tracks across genres, all CC-BY (just credit Kevin MacLeod in your game and link incompetech.com). Used in roughly half of all indie YouTube videos in existence — but for good reason.

Best for: a more curated alternative to Jamendo. Browse by genre, filter by license. Mostly CC-BY and CC-BY-SA. Lots of indie / experimental tracks that don't sound like every other "epic adventure" stock score.

Best for: bigger catalog than incompetech. Free for non-commercial use; commercial requires Jamendo's licensing tier. Read carefully before using in a paid game.

Best for: composing your own simple tracks if you don't read music. Built by Terry Cavanagh (VVVVVV, Super Hexagon) for non-musicians. Click notes on a piano roll, pick instruments, export. Genuinely the lowest-friction way to make a "good enough" original track.

Best for: trimming, normalizing, removing background noise, basic effects. The standard audio editor. Not a real DAW — multitrack composition is technically possible but slow.

Best for: a real DAW for the cost of a video game. Lifetime license, no subscription. The default upgrade path once Audacity stops fitting. Personal license is honor-system; commercial license is $225 once.

Best for: a free DAW for tracker-style composition. Built-in synths, beat patterns, sample-based composition. The interface is dated but the output can be excellent for chiptune / electronic styles.

Best for: NES / chiptune music with the actual NES sound chip emulated. If you're making a Pico-8 or NES-style game, this gets the right "feel" instantly.

Best for: high-quality TTS for short character barks ("Got it!", "Watch out!", "Level complete"). The free tier is enough for a small game with limited dialogue. Read the commercial use terms before shipping.

Best for: running TTS locally with no usage limits, if you have a GPU and patience for setup. Quality is below ElevenLabs but acceptable for retro / robotic voices.

Why: playing the exact same coin-pickup SFX 20 times in 5 seconds sounds robotic. Add ±5% pitch jitter on each play and it sounds organic. Implementation example in the platformer walkthrough's AudioBus prompt.

Why: hard cuts between tracks (level transition, boss start) are jarring. A 1.5-2s linear crossfade — fade old track volume out while fading new track in — is the basic dynamic music technique that elevates a prototype.

Why: separate volume sliders for SFX vs music are the absolute floor of audio settings. Players notice the absence. Most engines (Unity AudioMixer, Godot AudioBus, Phaser SoundManager) make this a 10-minute setup.
