From Recording to Readable Record

An audio file is a terrible system of record. The interview that shaped the article, the focus group behind the product decision, the client call where scope was agreed — they're all trapped in MP3s nobody will replay. When someone asks for the record, what they want is a document: readable, paginated, attributable, fileable.

Castmagic gets you there in one pass: upload the audio (or paste a link), review the speaker-labeled transcript, and export a formatted PDF with a cover page, headers, and page numbers. The recording's content becomes a document that can be read in five minutes, shared without explanation, and found again next quarter.

Recordings that deserve documents

Journalist interviews that editors and fact-checkers need on paper. Research sessions and focus groups headed for the appendix. Coaching calls clients want to revisit. Oral histories being archived. Board calls and client meetings that belong in the record. If the audio matters beyond the moment, the PDF is its durable form.

A document, not a dump

The export is formatted like a deliverable: cover page with the recording title, page numbers and headers throughout, each speaker turn labeled, timestamps optional. Whether the recording runs twenty minutes or three hours, the document holds its structure.

Accuracy you can sign off on

Before exporting, the transcript is fully editable — correct terms, rename speakers, set custom spellings that persist across recordings. For multilingual work, the transcript can also be translated into any of ten languages and exported as a PDF in the target language, with speakers and timestamps preserved.

And the summary to go with it

The person who asked for the transcript usually wants the summary too. Castmagic's AI presets draft executive summaries, key takeaways, and action items from the same transcript — attach them to the PDF and the record is complete.

Frequently Asked Questions

Last updated June 2026 by the Castmagic team

How do I convert an audio file to PDF?

Upload the audio file to Castmagic (or paste a link to it), wait a few minutes for transcription, then choose PDF from the download menu. You'll get a professionally formatted PDF document with a cover page, headers, and page numbers.

How accurate is the transcription?

Castmagic uses state-of-the-art speech models with support for 60+ languages, automatic language detection, and speaker labeling. Clear single-speaker audio typically transcribes well above 95% accuracy, and a custom-vocabulary list keeps brand names, product names, and industry jargon spelled correctly.

What formats can I download besides PDF?

Every transcript exports to six formats from the same menu: plain text (TXT), SubRip subtitles (SRT), WebVTT captions (VTT), a formatted PDF document, an editable Word document (DOCX), and a structured spreadsheet (CSV) with per-utterance speakers and timings.

Is this free to use?

Castmagic offers a free tier so you can convert a audio file and try the full workflow. Volume use — multiple files per week, longer recordings, and AI-generated content output — is available on paid plans.

Which audio formats can I convert to PDF?

MP3, WAV, M4A, and other common formats — upload the file directly or paste a link to where it's hosted.

Does the PDF show who said what?

Yes — every speaker turn is labeled. Speakers are detected automatically and you can rename the labels to real names before exporting.

Can I get the PDF in a different language than the recording?

Yes — translate the transcript (ten target languages including Spanish, French, German, and Japanese) and export the translated PDF with the same structure and timestamps.
