To transcribe GarageBand recordings automatically, export your audio as MP3 or WAV (Mac: Share, then Export Song to Disk; iOS: Share, then Song), then upload it to Sonix. Sonix delivers up to 99% accuracy on clean audio, processes recordings up to 10x faster, and returns a time-stamped, speaker-labeled transcript in under five minutes per hour of audio (processing time varies with file size, quality, and demand).
GarageBand has no built-in speech-to-text transcription. An external automated transcription service is required for any spoken audio, including podcasts, interviews, voiceovers, or narration.
GarageBand is a popular free recording tool built into every Mac, used by podcasters, journalists, content creators, and musicians who record voiceovers or narration. The recording quality is excellent, but the moment you need a searchable text file, whether for show notes, blog content, subtitles, or documentation, there is no GarageBand audio transcription feature inside the app itself. Every word spoken in your session sits locked in an audio file until you move it to a transcription tool. Converting a GarageBand recording to text is a two-step process: export and upload.
This guide covers the full workflow: how to export audio from GarageBand on both Mac and iOS, how to upload it for automated transcription, and how to get a clean, accurate transcript without spending hours listening back to your own recording.
TL;DR: GarageBand has no native transcription. Export your recording as MP3 or WAV (Mac: Share, then Export Song to Disk; iOS: Share, then Song), upload to Sonix, and receive a searchable, speaker-labeled transcript in under five minutes per hour of audio. Full steps below.
GarageBand does not include a built-in speech-to-text transcription feature. The platform’s Score Editor converts MIDI performances into music notation, which is a different type of transcription aimed at musicians, but there is no tool inside GarageBand to convert spoken audio, podcast dialogue, interviews, or voiceovers into a text document. To generate a transcript from any GarageBand recording, you need to export the audio file and upload it to an external automated transcription service.
This is true for both GarageBand on Mac and GarageBand on iPhone and iPad. Neither version of the app generates text from speech.
Before diving into the steps, here is how the two-step process works end to end:
Stage 1: Export from GarageBand
Stage 2: Upload to Sonix
Stage 3: Transcript ready
Stage 4: Review and export
The bottleneck is usually the GarageBand export step, particularly on iOS where the Share menu has a few extra taps. Everything after that is straightforward.
GarageBand on Mac gives you direct access to MP3 and WAV export, both of which are ideal for automated transcription.
The export process runs quickly: most podcast episodes or interview recordings finish exporting in under a minute on modern Mac hardware.
Note: If your GarageBand project has multiple tracks, for example separate tracks for host and guest microphones, mix down to a single stereo file before exporting. Go to File, then Save, then use Share, then Export Song to Disk to flatten everything into one file. If you need per-speaker audio files for more precise speaker diarization, export each track separately and upload them individually to Sonix.
GarageBand on iOS uses a Share-based export workflow that is slightly different from Mac.
iOS note: GarageBand for iPhone and iPad does not offer direct MP3 or WAV export. Sonix accepts the default AAC/M4A format without any conversion.
WAV (24-bit)
MP3 (160–320 kbps)
AIFF
AAC / M4A
For most spoken-word recordings, including podcast episodes, interviews, and voiceovers, MP3 at 160 kbps or AAC at 256 kbps delivers accuracy comparable to WAV. The main advantage of WAV or AIFF is when the recording contains heavy sound design, music beds at high volume, or multiple simultaneous speakers with significant audio overlap. For less common formats, see all supported audio formats on the Sonix site.
Once you have the exported audio file, the upload and transcription process takes just a few minutes.
Sonix at a Glance
Sonix is the practical choice for podcasters, journalists, and content teams who record regularly in GarageBand and need accurate, searchable transcripts within minutes of finishing a session. The 54+ language coverage makes it a strong option for international creators distributing across language markets. Teams in healthcare, legal, or financial media get SOC 2 Type II certification and HIPAA compliance via Medical Sonix built in, with no separate vendor evaluation required for transcription security.
Steps:
Sonix runs automated transcription at 10x faster transcription. A 30-minute podcast interview is typically ready in under three minutes. A 90-minute recording typically completes in under nine minutes. You will receive a notification when the transcript is complete.
Speaker diarization is the most valuable feature for podcast producers and interviewers: it automatically separates the transcript by individual voice, so host and guest dialogue is labeled throughout the document rather than appearing as one undifferentiated block of text.
For a standard two-person podcast interview exported from GarageBand as a single mixed file, speaker diarization typically handles the separation cleanly. For recordings with three or more voices, or sessions where multiple speakers talk at the same time, the time-stamped editor makes it easy to identify and correct any boundary errors.
A 5–10 minute edit in the Sonix editor is faster than re-listening to the full recording and produces a transcript ready to publish.
If your team uses a specific workflow tool, check Sonix’s integrations to push transcript output directly without manual file transfers.
The quality of the transcript depends heavily on the quality of the source audio. GarageBand gives you fine-grained control over your recording setup. Here are the settings that matter most for automated transcription.
Use a dedicated microphone, not the built-in Mac or iPhone mic. The built-in microphone on most Apple devices picks up keyboard noise, room echo, and background hum that degrades transcription accuracy. Even a mid-range USB microphone ($50–$100) dramatically improves speech clarity. In GarageBand, select your external microphone as the input source in Preferences (Mac) or Settings (iOS).
Record in a quiet environment with echo reduction. Rooms with hard surfaces (tile floors, bare walls) create echo that automated transcription interprets as overlapping speech. Recording in a treated space, or even sitting in a closet surrounded by clothing, reduces echo substantially without any equipment changes.
Set input gain correctly. In GarageBand on Mac, watch the level meter on your audio track while recording. Aim for peaks in the –12 dB to –6 dB range. Levels that consistently peak above –3 dB risk clipping (distortion), which permanently damages transcription accuracy and cannot be fixed in post-processing.
Separate tracks for each speaker when possible. If you record a podcast guest via a separate microphone or audio interface channel, keep each speaker on their own GarageBand track. Export each track as a separate file and upload them individually to Sonix. Per-speaker audio files give the transcription engine the cleanest possible signal for each voice, reducing cross-contamination between speaker turns.
Avoid music beds under interview dialogue. Background music added in GarageBand, even at low levels, reduces the signal-to-noise ratio of the speech track and can cause transcription errors. If you use intro or outro music, ensure the music and speech tracks are not overlapping in the exported file.
1. Exporting the GarageBand project file instead of the audio file. GarageBand’s native project format (.band) is not an audio file and cannot be uploaded to a transcription service. Always export using Share, then Export Song to Disk (Mac) or Share, then Song (iOS) to create a playable audio file.
2. Using low-bitrate compression. Exporting MP3 at 64 kbps or below noticeably degrades speech intelligibility. Set your MP3 quality to High (160 kbps) or Highest (320 kbps). For AAC from iOS, the default 256 kbps setting is fine.
3. Forgetting to mix down multi-track projects. If your GarageBand session has separate tracks for host, guest, music, and sound effects, the export step flattens all of them into a single file. Verify that all tracks are enabled and properly balanced before exporting: any muted or soloed tracks will affect what ends up in the transcript.
4. Selecting the wrong transcription language. Uploading an English recording but selecting a different language produces an unreadable output. This happens more often than expected when users rush through the upload step. Double-check the language selector before starting transcription.
5. Sharing an unreviewed transcript. Automated transcription is highly accurate on clean recordings, but proper nouns, technical jargon, and overlapping speech introduce errors that a quick review catches. A 5-minute edit in the Sonix time-stamped editor is faster than re-listening to the full recording and produces a transcript ready to publish.
Transcribing your GarageBand recordings automatically delivers measurable returns that audio alone cannot. A single 45-minute podcast episode generates roughly 6,000–8,000 words of transcript: the equivalent of two to three full blog posts, a month’s worth of social media quotes, and complete show notes, all without writing a word from scratch.
Time savings: Manual transcription takes 4–6 hours per hour of audio. Automated transcription via Sonix typically completes in under five minutes per hour of audio. For a weekly 45-minute podcast, that is a significant reduction in production overhead.
SEO impact: Transcribed show notes give podcast episodes searchable, indexable content that audio alone never achieves. Episodes with full transcripts rank for long-tail search terms that attract listeners who would never find the show through podcast directories alone.
Accessibility: Full transcripts make podcast content accessible to deaf and hard-of-hearing audiences. The World Health Organization estimates that a large portion of the global population lives with disabling hearing loss: transcripts ensure your content reaches that audience.
Content repurposing ROI: A transcript unlocks blog, email, social, and video caption use simultaneously.
macOS offers built-in speech tools including Dictation, Voice Memos, and Notes. Here is how they compare to Sonix for GarageBand users.
macOS Dictation is primarily designed for entering text while you speak in real time, such as composing emails or documents. It is not designed for uploading and transcribing pre-recorded audio files.
Voice Memos on Mac (macOS 15 or later, Apple silicon) and Notes on Mac (recent versions) can generate transcriptions of recordings made within those apps. Availability depends on macOS version, device, region, and language. These are useful for recordings captured natively in those apps.
How Sonix differs for GarageBand workflows:
For GarageBand users who need to transcribe exported audio files with speaker labeling and professional export formats, Sonix provides a complete workflow that goes beyond what is available in the macOS native toolset.
If you produce a regular podcast series recorded in GarageBand, the Sonix API lets you automate file upload and transcript export without manual steps. Connect it to your GarageBand export folder and transcripts appear automatically after each session.
Once your GarageBand recording is transcribed, Sonix can translate the transcript into any of its 54+ supported languages. This is practical for podcasters distributing to international audiences or content creators repurposing audio into written posts across multiple language markets.
If you publish a video version of your podcast or YouTube clips from your episodes, export the Sonix transcript as SRT and attach it to the video. This takes under a minute and makes your content accessible to hearing-impaired audiences and non-native speakers, and improves YouTube SEO.
A DOCX transcript of every podcast episode, stored in Google Drive or Notion, creates a searchable archive that your content team can mine for blog posts, social quotes, newsletter sections, and PR pitches. For healthcare, legal, or financial podcast producers, Sonix’s SOC 2 Type II certification and HIPAA compliance via Medical Sonix ensures the transcript workflow meets the same data security standards as the rest of your production stack.

No. GarageBand includes a Score Editor that converts MIDI instrument data into music notation, but there is no speech-to-text feature for recordings of spoken dialogue, interviews, or voiceovers. Transcribing GarageBand recordings to text requires exporting the audio file and using an external automated transcription service.
For Mac, MP3 at 160 kbps or higher is the most practical choice: compact file size, fast upload, and reliable accuracy. WAV or AIFF works equally well and produces the highest fidelity. For iOS GarageBand, the default AAC/M4A export at High Quality is fine; Sonix accepts M4A without any conversion.
With Sonix, processing runs at up to 10x real-time speed. A 30-minute podcast recording is typically ready in under three minutes. A 60-minute recording typically completes in under five minutes. Processing time can vary with file size, audio quality, and demand. You will receive a notification when the transcript is complete.
Yes. Sonix offers a 30-minute free trial with no credit card required, which is enough to transcribe a short interview segment or podcast episode and verify accuracy on your specific audio quality.
Yes. After uploading to Sonix, enable speaker diarization in the editor. Sonix’s AI automatically detects voice changes and segments the transcript by speaker. You can rename each label, such as “Host” or “Guest Name,” so the final document clearly identifies who said what throughout the conversation. For best results, record each speaker on a separate GarageBand track and export as individual files before uploading.
