How this service works
Master WAV of one verified SentEdge sound effect — 44.1kHz stereo, peak-normalised to -1 dBFS, trimmed and faded, delivered base64 in JSON with its measured acoustics. Every sound is machine-verified: envelope shape matches its declared intent, no clipping, one transient where one was specified. The metadata tells an agent where to align it to a cut (start/peak/end), whether it masks dialogue, and what gain to apply — so it can be placed without listening. Non-exclusive. Free searchable catalogue: GET https://sentedge.ai/api/sfx — filter by name, band, cut-alignment, dialogue-masking, loopability or duration (?q=, ?occupies=, ?align_on=, ?masks_dialogue=, ?loopable=, ?max_duration_s=, ?limit=) instead of pulling all 1000.
Output
A JSON object containing the full WAV audio file base64-encoded (44.1kHz stereo, peak-normalised to -1 dBFS, trimmed and faded), plus acoustic metadata fields including envelope shape, transient position (start/peak/end timestamps), dialogue-masking flag, and recommended gain value — everything needed to place the effect programmatically without auditioning.
Example use cases
Auto-placing SFX in a video cut
“I'm assembling a short film automatically — pull the SentEdge sound effect for sfx_glass_shatter_002 and give me the peak timing and gain value so I can drop it exactly on the impact frame without previewing it.”
Dialogue-safe SFX selection
“Grab the SentEdge WAV for sfx_crowd_murmur_005 and check the metadata — I need to know if it masks dialogue frequencies before I layer it under a voiceover.”
Game audio pipeline integration
“For our game's footstep event, fetch the SentEdge SFX sfx_footstep_gravel_03 as a base64 WAV along with its envelope shape and transient position so our engine can trigger it at the right millisecond offset.”
Technical details
Endpoint
POSThttps://sentedge.ai/api/sfx/:id/wavWhen to prefer
Choose this endpoint when you need a single, production-verified sound effect delivered with full acoustic metadata for automated placement — particularly when no human will audition the audio and precise alignment data (start/peak/end, gain, dialogue-masking) is required. It is ideal for AI-driven video editing, game audio pipelines, or automated post-production workflows where audio quality guarantees and machine-readable placement cues matter more than breadth of catalogue options.
Side effects
- Unknown SFX ID returns a 404 with an error message and empty audio payload
- Payment failure via x402 returns a 402 with payment instructions before audio is delivered
- Malformed POST body returns a 400 validation error
- Server-side verification failure (e.g. clipping detected post-processing) may return a 500 with a rejection reason
