Shows a live wave as you speak and lets you save as MP3. A browser extension that visualizes any audio playing
Technically, an MP3 is a "compressed container." You cannot "download" a live wave as an MP3 until the recording is finished or "finalized," because the file needs a header that tells the player how long the audio is. Technically, an MP3 is a "compressed container
pip install numpy matplotlib sounddevice scipy pydub
Best for recording and seeing the wave in real-time.
