Question: Is there a platform that allows me to edit audio files online, including trimming and joining clips?

Descript is a general-purpose video and podcast editing tool that uses AI to automate some of the grunt work. It's got multitrack audio editing, AI-selected clips, automatic transcription and one-click captions. You can trim and join clips, too, and it's a good all-purpose tool for editing podcasts and videos. Descript offers a free plan with limited features and a paid plan starting at $12 per person per month.

Another good option is Riverside. This online studio is geared for good-sounding podcast and video recording and editing. It's got AI transcription in more than 100 languages, automated show notes and the ability to create clips from recordings. Riverside also lets you trim and join clips, and its text-based editor lets you edit audio recordings with fine-grained control.

Adobe Podcast is another powerful tool for audio editing. It's got features like Enhance Speech to remove background noise and echo, and Mic Check to optimize microphone performance. Adobe Podcast also has a beta version of Podcast Studio that lets you record, edit and enhance audio directly within the web app. It's geared for content creators who want to produce high-quality audio without having to do a lot of extra work.
