Why this exists
A latency slider backed by a finite official map
Transformers documents four supported lookahead values and their streaming delays. The planner exposes that trade-off directly and checks the audio format before code is copied.
Nemotron 3.5 ASR companion
Choose a Nemotron 3.5 ASR streaming latency and export the code
Map Nemotron 3.5 ASR lookahead tokens to the official 80–1120 ms latency choices, inspect a WAV locally, and export a streaming configuration.

Working tool
Build a verified workflow
Set the delay your product can tolerate. The planner returns the matching lookahead value, audio preflight, and copy-ready Transformers code.

Official latency map
Maps 0, 3, 6, and 13 lookahead tokens to documented delay.
WAV header check
Reads sample rate and channel count locally without uploading audio.
Streaming code
Exports preprocessing and Transformers configuration together.
Three steps
From choice to portable output
No account screen or fake generation state gets between the search intent and the task.
- 1
Choose a supported latency and transcription scenario.
- 2
Optionally inspect a WAV header in the browser.
- 3
Copy the lookahead, preprocessing, and streaming code.
Frequently asked
Limits are part of the product
Which lookahead values are supported?
The cited Transformers documentation maps 0, 3, 6, and 13 tokens to 80, 320, 560, and 1120 milliseconds.
Does a larger lookahead improve accuracy?
It gives each chunk more future audio context, trading extra delay for potentially better recognition.
Is my audio uploaded?
No. The optional WAV check reads only the local header in your browser.
Does this site transcribe audio?
No. It generates an auditable local streaming configuration and never labels a config as a transcript.
