Making videos

The Slideshow maker turns photos and music into a video with transitions, and Audio to video puts a song, podcast or voice clip on screen with a picture and a moving waveform. Both make WebM files in your browser, ready for YouTube.

Before a call or recording

Mic test shows a live level meter and lets you hear a playback, and Speaker test plays left, right and bass tones so you can check each channel. Audio recorder saves your voice straight from the browser.

Editing sound

Audio cutter trims a clip to the part you need, Audio joiner combines several files, and the normaliser evens out volume and trims silence. Each can save MP3 or WAV. Video to audio saves a video's soundtrack, and the Audio converter turns whole batches of files into MP3, WAV, OGG or WebM.
