Whether inspecting AI-generated voice responses from ElevenLabs or embedding sound effects in web apps, this tool provides instant audio playback without server roundtrips.
Frequently Asked Questions
How do I play and decode a Base64 audio string?
Paste your Base64 audio string or Data URI (e.g. data:audio/mp3;base64,...) into the input box. The tool loads the sound directly into an HTML5 audio player and lets you download the audio file.
Which audio formats are supported?
Our player and converter support MP3, WAV, OGG, M4A, AAC, and FLAC audio files.
Is my audio file uploaded to a remote server?
No, all audio decoding and playback happens 100% in your local browser sandbox.
How do I embed a Base64 audio clip in HTML?
Use '<audio controls src="data:audio/mp3;base64,..."></audio>' to embed sound effects without external file dependencies.
Can I convert text-to-speech API responses in Base64?
Yes! AI Voice and TTS APIs (such as OpenAI Audio, ElevenLabs, and Google TTS) return generated audio as Base64 strings. You can paste them here to listen and download.
How can I download the decoded audio?
Click the 'Download Audio File' button to save the audio directly to your computer as an .mp3, .wav, or .ogg file.
