Use Decopy's M4A to text converter to turn files up to 500 MB into searchable transcripts with timestamps, speaker labels, and TXT download.

An M4A recording may contain exact wording, names, numbers, and explanations that should not be reduced to memory alone. Upload it to turn speech into text online and keep a written record that stays close to the original conversation.

Spoken thoughts often include pauses, corrections, repeated points, and ideas introduced out of order. M4A transcription gives you a written starting point for separating questions, explanations, examples, and conclusions.

An audio file is difficult to comment on, approve, or discuss with someone who was not present. Use audio to text converter for M4A files to create a shared record that colleagues, clients, or collaborators can read and review together.

Decopy combines M4A transcription with tools for reviewing source audio, organizing conversations, finding evidence, and preparing the transcript for its next use.
Upload an M4A file up to 500 MB directly from your device. The M4A to text converter works with the recording you already have, so you do not need to create an MP3 or WAV copy before transcription.
The generated M4A transcript stays connected to the recording through timestamps and audio playback. When a name, number, quote, or technical term needs checking, return to the relevant moment instead of searching through the full recording manually.
Turn on Identify Speakers before starting an interview or meeting transcription. Decopy separates recognized voices with speaker labels, and you can rename, add, or replace speaker names while reviewing the conversation.
Use AI Chat to ask focused questions about the completed transcript. Locate a participant's explanation, an unresolved issue, or a supporting example, then return to the transcript and audio when the source wording needs verification.
Long recordings rarely arrive in a clean written structure. Generate a summary to identify the main points, or use a mind map to see how topics, arguments, and examples connect before preparing notes or a draft.
Translate the completed transcript into an available target language when the recording needs to be understood by another audience. Download the final M4A transcript as a TXT file for documents, notes, research files, or further editing.



Beyond individual interviews, meetings, lectures, and voice notes, M4A transcription also supports teams that work with recorded audio on a regular basis.
Transcribe M4A to text for free with up to 10 daily transcriptions for audio no longer than 30 minutes. The upload area displays the current free allowance and limits.
See the current upload limit, free allowance, and recording-length requirements before submitting the file.
Keep the full transcript available while using timestamps, playback, speaker labels, summaries, mind maps, and AI questions. This makes it easier to explore the recording without losing the path back to the source.
Use the M4A to text converter in a supported desktop or mobile browser. You do not need to install a dedicated transcription application before uploading and reviewing the file.
