Need the soundtrack of a video on its own? Attach the FLV, ask ToolGPT for the audio as MP3, and download a file that plays anywhere audio does. The picture is left out, and the work happens in your browser.
Open ToolGPT and press the + button beside the message box, or drop the video into the chat. No account is needed to start.
Type “Save the audio as MP3”. You can name a sample rate too, and a bitrate for compressed formats; anything you leave out follows the video's own audio.
The audio file appears as a card in the chat with a download button. The video is not changed.
FLV files saved from old streaming sites hold talks, music and broadcasts that are easier to keep as audio than as a video few devices can play. Old FLV files often have low-bitrate sound, and converting to MP3 keeps that quality but cannot improve it.
The sound is extracted and converted in your browser with a WebAssembly build of FFmpeg, so the video is not uploaded to a server. Only the audio is written to the new file.
A conversion changes the format and nothing about the sound itself: the length and loudness stay as they were. If you only need part of it, ask ToolGPT to trim the audio file afterwards.
FLV, or Flash Video, is the container Adobe Flash Player used to stream video on websites. It usually carries H.264 or an older Flash codec, with MP3 or AAC sound. Since Flash was retired, browsers and most devices no longer play FLV, so old files usually need converting before anyone can watch them.
MP3 is the best-known compressed audio format, playable on almost every phone, computer, car stereo and music app. It keeps files small by discarding sounds the ear is unlikely to notice. That saving is permanent: an MP3 cannot get its lost detail back, and at low bitrates the loss can be heard.
No. ToolGPT extracts the sound in your browser. Your messages go to the AI assistant, but the FLV file stays on your device.
Yes. Ask for a sample rate, and for compressed formats a bitrate such as 192 kbps. Settings you leave out match the video's own audio.
Yes. After the conversion, ask ToolGPT to trim the audio file, for example “keep only 0:30 to 1:45”, and drag the range on the trim card.
