Formats: the format list shows only what this browser can encode. MP3 and FLAC use an encoder that downloads the first time you choose them. M4A (AAC) is not available in every Firefox version.
Memory: audio is decoded in full, about 23 MB per minute of 48 kHz stereo, so long recordings can be slow on phones. Files that would need more than about 1 GB once decoded (about 45 minutes of 48 kHz stereo, or 90 of mono) are refused before decoding.
