search_sounds | Free-text search over the SFXMint library of free CC0 sound effects. Use it for sound descriptions, additional constraints or gaps left by another tool. Choose get_role_sound for a named event or get_sound_set for multiple events when that fits the task; these are task branches, not a fixed sequence. Hard constraints (duration, loop, format, excluded words) always apply. results hold sounds whose params: query*, category, limit, max_duration_ms, loop, format |
get_role_sound | Choose this when the task calls for a sound for a named event or interaction — a button click, purchase success, error beep, level-up, dialogue blip, notification. Pass the role as plain words: role ids (click, success, purchase-success, dialogue-blip, notification…) and common aliases (button click, ka-ching, jump scare, text blip…) are all accepted. Returns a qualified candidate for that role wh params: role*, style, max_duration_ms, loop, format |
get_sound | Get full metadata for one sound by slug, including download URLs, description and measured acoustics (attack/tail/brightness + character labels). params: slug* |
get_sound_set | Get a coherent set of sounds for an app or game in one call — one sound per role, with format metadata, hashes and stable download URLs. Use it when the task needs a whole kit; use get_role_sound for one event. Listen to the files in context. Sets include UI styles, game and app scenarios, acoustic-drum-kit, animal-calls (15 isolated calls), and dungeon-traps (6 isolated mechanisms). params: format, set |
studio_list_link | One link to SFXMint Studio for every sound the library lacks in this task: pass each missing sound as a short description and give the user the returned user_message once, instead of one link per sound. The page lists them ready to make one by one, heard before paying; nothing is made or charged here, and no API key is needed. params: sounds* |
generate_sound | Make an individual sound effect from a description when the library has nothing suitable (search_sounds has no full match and its closest sounds do not suit; it then returns generate_available). For continuous environmental beds or instrumental background music, use generate_ambience or generate_music when offered. Needs an SFXMint API key and uses the account's 1 free try first, then credits or a params: prompt*, duration_s, variations, enhance, variations_of |
get_generation | Check a generation started with generate_sound, generate_ambience, generate_music or change_sound: status, kind and fresh download links for the finished takes, including loop_url when a loop was made. params: order_id* |
change_sound | Change one take of a generation this account made, from the take itself: say what is off in the user's words (change, any language) or name the action. Three versions come back (a light, medium and strong change; for a loop, three seams) as CC0 WAV files. Free: no generation is used and no plan is needed. When the words ask for a different sound rather than a change to this one, it answers no_acti params: order_id*, take*, change, action |
generate_ambience | Make a continuous environmental sound bed such as rain, waves, a forest or a crowd, not a musical track or an isolated event. Makes 30-second CC0 WAV takes and attempts seamless loops. Needs an SFXMint API key and credits or a plan; sound-effect free tries do not apply. Missing access returns website_url for Studio Ambience; payment_required also returns buy_url. Returns order_id, files and loop_u params: prompt*, duration_s, variations, enhance |
generate_music | Make instrumental background music (BGM), including ambient music, for an app or game; for environmental sounds use generate_ambience. Makes 30-second CC0 WAV takes and attempts to extract repeating musical loops. Needs an SFXMint API key and credits or a plan; sound-effect free tries do not apply. Missing access returns website_url for Studio BGM; payment_required also returns buy_url. Returns or params: prompt*, duration_s, variations, enhance |
