Files are imported by dragging and dropping them onto the interface, after which they can be processed and exported according to the specified settings. Operations can be defined using text input, allowing multiple independent actions to be executed sequentially. The software enables fast editing without the need for decoding and re-encoding the audio.

  Mofi – Content-aware fill for audio to change a song to any duration2023 · mofi.loud.red · ▲708

  I worked on a web service that allows you to import a song and define a target length that the song will be shortened or lengthened to. It does this by analyzing the song and finding repeating audio patterns. This is helpful for making any song match a video or performance with a set duration. You can also specify areas of the song to prefer or avoid. An example is available here: https://mofi.loud.red/edit/8bd3fdf780f8c3927e41029f3b957f8a7... The cool thing is that after the song is analyzed on the server, the client can recompute and preview the results completely…

  RM2000 Tape Recorder2025 · rm2000.app · ▲102

  RM2000 Tape Recorder makes it stupid simple to grab audio samples and organize them: just record the sample, give it a title (and maybe some tags), and it is saved neatly into a directory of your choosing. I'm a huge datahoarder and have always appreciated tools / services like PureRef and Are.na which help me make sense of everything I collect. Those services concern themselves with images and video - I wondered, why can't the same be done with music and audiofiles? I actually got the inspiration for the filenaming scheme from the Emacs Denote package - every sample is saved in the…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Tapflow 2.0▲1,125

  We built Tapflow for devs, designers, PMs, and tech folks who’ve been sitting on internal docs, templates, and systems — but never productized them. Upload a PDF, notes, or workshop deck, and Tapflow drafts a structured product (with chapters, teaser and pricing plans). It’s good for AI kits, onboarding guides, design systems, and frameworks. You can sell through Stripe, LemonSqueezy, or PayPal. Real-time collaboration is in early beta. No site builder, no LMS — clean design and just focused tools to ship. Fully bootstrapped and just launched on PH today →…
