Subreddit rules check

Can you promote here?
The written rules take no clear position, which is NOT permission: unclear communities enforce norms through removals instead of rulebooks. Sort by top, study which builder posts survived and how they were framed, and when in doubt ask the mods.
From the rules · Rules don’t clearly address self-promotion — ask the moderators before posting commercial products or linking your own site.
Links
No explicit link policy. Default to no URL: link-plus-young-account is one of the most common automated removal patterns on Reddit.
What this community rewards
Dominant post formats: discussion, question, showcase
Headline = concise technical noun + descriptor (e.g., “ECG Wavelet” or “New wavelet kernel based on lognormal spectrum”). Body = neutral/technical, medium length, include equations, plots and code for reproducibility. Tone = academic/engineering. Posts that show original methods, clear figures and working code get upvoted; vague marketing or one-line product plugs are ignored or removed.
Arriving in the local format matters: cross-posting the same text everywhere reads as tourist instantly. The wider method is in the Reddit playbook.
Classified mechanically from the community's published rules and recent top posts, last checked July 2026. Rules change and moderators have the final say: verify at r/signalprocessing's rules page before posting anything that matters.
Thread Otter checks this before every send
These profiles power the product: promo-banned communities never receive a promotional draft, drafts arrive in the local format, and a fact-check gate plus human pacing protect the account doing the talking.
