Zwind vs Cepstrum

Turn your iPhone or iPad into a local WebDAV server and personal content hub. Zwind maps local files, SMB/NAS, cloud drives, RSS/OPML feeds, web media, and Emby libraries into one WebDAV-style resource tree, so files, feeds, web lists, media, and links can be browsed, read, played, streamed, and shared. Zwind is more than a file server or player. It is a lightweight workspace with built-in WebDAV Browser, Web Browser, Feed View, Video Player, Music Player, Image Viewer, Text Editor, Markdown Reader, Bookmarks, and more. Map content into Zwind instead of copying it into the app, then read, play, edit, search, cast, or continue in third-party WebDAV clients and players. Background WebDAV server operation is supported. Start free with one WebDAV server. Upgrade to Zwind VIP for multiple servers, advanced resolvers, and richer content workflows. Selected resolvers can also be unlocked separately. PERSONAL WEBDAV SERVER Create a WebDAV server on your iPhone or iPad. Map local folders or connect SMB, NAS, and cloud storage. Share files over LAN and access them from browsers, players, file managers, or any WebDAV-compatible app. MULTI-SOURCE RESOURCE TREE Bring local folders, SMB/NAS, iOS Files cloud folders, Quark Drive resources, RSS/OPML, web media, and Emby libraries into one unified directory. To you and third-party clients, they open like normal folders. RESOURCE PROJECTION & RESOLVERS Zwind projects feeds, search results, web lists, cloud-drive-like sources, and media libraries into virtual WebDAV directories. Supported resolvers: * RSS Projection: RSS, Atom, podcasts, and OPML imports as readable feed resources. * Quark Search Import: search and save supported Quark Drive shares. * Web Media Projection: parse web media sites into clean virtual folders, so webpage media can be browsed, read, or played like files. * Emby Library Projection: browse Emby libraries as WebDAV directories with metadata, filters, pagination, search, and playback. FEED VIEW Feed View is Zwind’s unified reading layer. Aggregate RSS, Atom, OPML, podcasts, YouTube channels, Reddit communities, and web sources connected through Web Media rules. Articles, images, audio, and video resources can appear together in one subscription timeline. WEB MEDIA PROJECTION With open .wm rules based on the ZWMP open standard, a few lines of declarative configuration can describe how a list page is detected and parsed. Turn webpages into browsable WebDAV directories and enjoy them inside Zwind. BUILT-IN APPS Use WebDAV Browser, Web Browser, Feed View, Video Player, Music Player, Image Viewer, Text Editor, Markdown Reader, and Bookmarks from one place. MEDIA, READING & FILES Play video and music, view images, read Markdown or text, and manage files. Supports queues, minimized playback, Picture in Picture for supported videos, subtitles, AirPlay, DLNA/UPnP casting, image zoom, media search, WebDAV URL bookmarks, folder flattening, file actions, and quick previews. SECURITY & CONVENIENCE Zwind’s WebDAV server runs locally on your device. You decide which directories to expose and whether visitors must enter username and password. Server Lock can require a password or Face ID before starting selected servers. PREMIUM The free version can run one WebDAV server. Upgrade to Zwind VIP to run multiple servers, unlock advanced workflows, and use the growing Resolver system.

That hum in your bedroom at night. The bass leaking through the wall. The "quiet" air purifier that isn't. Cepstrum shows you exactly what you're hearing — a live picture of sound, measured with nothing but your iPhone. SEE THE NOISE, NOT JUST HEAR IT A real-time spectrum from deep bass to the top of your hearing, with a sharpened spectrogram that turns tones into crisp lines. Point it at a mystery sound and get its fingerprint: the fridge hum at 50/60 Hz, the fan bearing whining at 4 kHz, the feedback frequency before it screams at your venue. KNOW HOW LOUD IT REALLY IS A proper sound level meter with A/C/Z weighting and Fast, Slow and Impulse response. Is the gym actually too loud? The restaurant? Your kid's headphones? Set the offset against a meter you trust and read real dB SPL — not a guess. PROVE THE DIFFERENCE Capture a measurement, overlay another, and read the change in decibels. Did the new windows cut the street noise? Is the replacement fan quieter than the old one? Before and after, one seat against another — the answer on screen, not in your head.
