voice-memo-export 0.2.0

A Python tool for exporting Apple Voice Memos effortlessly. Provides a simple solution to back up your voice memos.

voice-memo-export

A Python CLI tool to export Apple Voice Memos on macOS to a directory of your choice, with customizable filenames.

Why this script?

Recording many voice memos on Apple devices will over time clutter every device synced via iCloud and eats into your iCloud storage. This tool gives you a clean local copy you can archive, organise, or back up however you want.

The script is non-destructive: original recordings in the Voice Memos library are never modified or deleted.

Features

• Command-line interface for quick exports
• Export all Voice Memos in one run
• Preserves original recording timestamps on exported files
• Flexible filename formatting using Jinja2 variables and filters
• Auto-detects the Voice Memos database location (overridable via --source)
• Skips files that already exist at the destination, so re-runs are safe
• Tested on macOS Monterey / Ventura / Sonoma / Sequoia / Tahoe

Prerequisites

• macOS Monterey (12) or later
• Python 3.12 or higher
• Poetry 1.8.0 or higher
• Full Disk Access granted to your terminal application (see below)

Granting Full Disk Access

Recent versions of macOS protect the Voice Memos database under TCC (Transparency, Consent, and Control). Without Full Disk Access, the script cannot read the source database and will fail with a permission error.

To grant access:

1. Open System Settings → Privacy & Security → Full Disk Access
2. Add your terminal application (Terminal, iTerm2, Warp, etc.)
3. Restart the terminal

If you run the script via an IDE's integrated terminal, that IDE needs the permission instead.

Installation

Install Poetry if you haven't already:

curl -sSL https://install.python-poetry.org | python3 -

Clone this repository:

git clone https://github.com/bulletinmybeard/voice-memo-export.git
cd voice-memo-export

Install dependencies:

poetry install

Usage

Basic usage

Run with default settings (exports to ~/Voice Memos Export):

poetry run vmexport

Run with custom settings:

poetry run vmexport \
  --output ~/Documents/VoiceMemoBackup \
  --format "{{ZDATE.strftime('%Y%m%d')}}_{{ZENCRYPTEDTITLE}}"

Get help:

poetry run vmexport --help

CLI arguments

Argument	Short	Description	Default
--source	-s	Path to the Voice Memos source directory	Auto-detected based on macOS version
--output	-o	Path to the export folder	~/Voice Memos Export
--format	-f	Jinja2 template for the exported filename	{{ZDATE.strftime('%Y%m%d%H%M%S')}}_{{ZENCRYPTEDTITLE|replace(' ', '_')}}_{{ZUNIQUEID}}

Output

Exported files keep their original .m4a extension; no transcoding is performed. The extension is appended automatically, so your --format template should describe the filename stem only (no .m4a needed).

If a file with the same name already exists at the destination, it's skipped. This makes incremental exports safe: run the command again later and only new memos are copied.

Filename format

The --format option customises the filename of each exported memo using a Jinja2 template.

Available variables

Variable	Description	Example value
{{ZDATE}}	Recording date and time (datetime object)	2024-03-17 14:30:22
{{ZDURATION}}	Duration in seconds (float)	180.5
{{ZENCRYPTEDTITLE}}	Memo title	Meeting Notes
{{ZCUSTOMLABEL}}	Custom label, if set	Important
{{ZCUSTOMLABELFORSORTING}}	Custom label used for sorting	Work - Project A
{{ZUNIQUEID}}	Unique identifier for the memo	A1B2C3D4-E5F6-G7H8-I9J0-K1L2M3N4O5P6
{{ZFLAGS}}	Internal flags (integer)	4

Filters and functions

Standard Jinja2 filters are available, plus a custom slugify filter added by this tool.

Filter / function	Description	Example usage	Example output
strftime()	Format a datetime	{{ZDATE.strftime('%Y-%m-%d')}}	2024-03-17
replace()	Replace characters	{{ZENCRYPTEDTITLE|replace(' ', '_')}}	Meeting_Notes
truncate()	Limit string length	{{ZENCRYPTEDTITLE|truncate(20, true, '')}}	Meeting Notes for P
slugify (custom)	Slugify a string	{{ZENCRYPTEDTITLE|slugify}}	ai-machine-learning-trends-2024
lower	Convert to lowercase	{{ZENCRYPTEDTITLE|lower}}	meeting notes
upper	Convert to uppercase	{{ZENCRYPTEDTITLE|upper}}	MEETING NOTES

When using these in the shell, escape special characters as needed.

Example templates

Basic, with date and title

{{ZENCRYPTEDTITLE}}_{{ZDATE.strftime('%Y-%m-%d_%H-%M-%S')}}

Result: My Voice Memo_2024-03-17_14-30-00.m4a

Using duration and a short ID suffix

{{ZDATE.strftime('%Y%m%d')}}_{{ZDURATION|int}}s_{{ZUNIQUEID[-8:]}}

Result: 20240317_180s_A1B2C3D4.m4a

Conditional formatting

{% if ZCUSTOMLABEL %}{{ZCUSTOMLABEL}}_{% endif %}{{ZDATE.strftime('%Y-%m-%d')}}

Result: Important_2024-03-17.m4a (when ZCUSTOMLABEL is set) or 2024-03-17.m4a (when it isn't)

Complex formatting

{{ZDATE.strftime('%Y-%m-%d')}}_{{ZENCRYPTEDTITLE|replace(' ', '_')|truncate(20, true, '')}}_{{ZUNIQUEID[-8:]}}

Result: 2024-03-17_My_Voice_Memo_Wit_A1B2C3D4.m4a

More example commands

Export all voice memos to the default location:

poetry run vmexport

Export to a specific folder with a custom filename format:

poetry run vmexport \
  --output ~/Downloads/VoiceMemoBackup \
  --format "{{ZDATE.strftime('%Y%m%d')}}_{{ZENCRYPTEDTITLE}}"

Export from a custom source path with a complex filename format:

poetry run vmexport \
  --source /path/to/custom/VoiceMemos \
  --format "{{ZDATE.strftime('%Y-%m-%d')}}_{{ZENCRYPTEDTITLE|replace(' ', '_')|truncate(20, true, '')}}_{{ZUNIQUEID[-8:]}}"

Use conditional formatting in the filename:

poetry run vmexport \
  --format "{% if ZENCRYPTEDTITLE %}{{ZENCRYPTEDTITLE}}_{% endif %}{{ZDATE.strftime('%Y-%m-%d')}}_{{ZDURATION|int}}s"

Troubleshooting

Unable to find the Voice Memos database

Make sure you've recorded at least one memo with the Voice Memos app. If the database still isn't found, point the script at it explicitly with --source.

Permission denied / operation not permitted

Almost always a Full Disk Access issue. See Granting Full Disk Access above. Remember to add the actual terminal binary you're running from, and to restart it afterwards.

Database is locked

Quit the Voice Memos app before running the export. The app holds an exclusive lock on the SQLite database while open.

Write errors at the destination

Confirm the path passed to --output exists or can be created, and that your user has write permission there.
