How to Share Stems and Masters With Clients: A Music Producer’s Buyer Guide (With Feature Checklist)

Stems and masters are some of the easiest files to send incorrectly. A client gets the wrong revision, downloads only half the stems, cannot open the folder structure, or asks you to “just email it” again because the link expired.

This buyer guide is written for music producers, mixing engineers, and small studios who regularly share:

• Mix stems (drums, bass, vocals, FX, instrument groups)
• Alt versions (instrumental, TV mix, clean, a cappella, performance tracks)
• Masters (WAV, plus MP3 references)
• Session deliverables (sometimes the whole project folder)

Use the checklist below to choose the right delivery method, then apply the same structure every time so clients know what to expect.

What matters when sharing stems and masters (the producer’s checklist)

1) Folder support (and whether it preserves your structure)

Stems are rarely a single file. You might send 20 to 120 WAVs plus a notes file. Look for a service that lets you upload a folder (or multiple files at once) and keeps your structure intact so the client sees something like:

• 01_Masters
• 02_Stems_48k24b
• 03_References
• ReadMe_Notes.txt

When the service flattens everything into one list, clients download the wrong items or miss files entirely.

2) Clear versioning (so “FINAL” stops happening)

Producers live in revisions. Your tool should make it easy to communicate what changed and which version is current. Even if the service does not have built-in versioning, you should be able to:

• Rename the transfer or link title to include the version (for example, “SongName v7 Mix Stems”)
• Add a short message with notes (for example, “v7: +0.8 dB vocal, de-esser tweak, new limiter”)
• Send a new link cleanly when needed (instead of re-uploading into a confusing thread)

3) Expiry controls (and whether you can extend later)

For client work, expiring links are a feature, not a limitation. You want enough time for approvals, but you also want old links to stop circulating. Look for:

• Auto-expiry you can set per transfer
• The ability to extend expiry without uploading again
• A clear expiry date visible to the sender (and ideally the recipient)

If you want a practical step-by-step on how expiry settings should work, see How to Create an Expiring Download Link (Auto-Expires in 10 Steps).

4) Password protection (when you are sending unreleased music)

Unreleased tracks and label work often require an extra layer. A password-protected link is a simple baseline control, especially if a link gets forwarded accidentally. Look for:

• Password protection on the transfer (not just on an account)
• Separate sending of password (for example, via text or a different channel)

5) Reliable downloads for non-technical clients

Your client should be able to click once and download. Pay attention to:

• Resume-friendly downloads (important for large ZIPs or many WAVs)
• A clean recipient experience (no confusing account signups)
• Consistency across browsers and mobile

6) File integrity (no conversion, no surprise compression)

Stems and masters must arrive unchanged. Avoid tools that “optimize” media. A good delivery method should:

• Keep WAV/AIFF files exactly as uploaded
• Not transcode audio
• Preserve filenames (your naming is part of the workflow)

7) Notifications and basic tracking (optional, but useful)

For tight timelines, it helps to know whether the link was accessed. Some services provide basic download notifications or simple activity indicators. Treat this as helpful, not essential, and always assume that “not seen” does not mean “not heard”.

8) Storage philosophy: transfer link vs cloud folder

Many producers use both:

• Transfer links for delivery (simple, time-limited, tidy)
• Cloud storage folders for ongoing collaboration (shared, persistent, often sync-based)

If you mainly need one-off delivery of stems and masters, a dedicated transfer link is usually cleaner than inviting clients into a long-lived cloud folder.

Feature checklist table: comparing common ways producers send stems

My recommended stem delivery workflow (simple and repeatable)

1. Export and label consistently. Example: SongName_120bpm_48k24b_VoxStem_v7.wav. Keep it readable.
2. Create a delivery folder. Separate Masters, Stems, References, Notes.
3. Include a ReadMe. List sample rate/bit depth, version notes, and what is in each folder.
4. Send as a transfer link with an expiry. For most clients, this is cleaner than granting cloud permissions.
5. Password-protect unreleased work. Send the password via a different channel.
6. Archive your own copy. Treat delivery as a snapshot. Do not rely on the transfer link as your only archive.

Which tool should you choose?

Use these quick rules of thumb:

• If you want the simplest client experience for one-off deliveries, choose a dedicated transfer link service with expiry and (optionally) password protection. You can send a file free or create a free account to set up a repeatable delivery routine.
• If you are collaborating continuously (shared edits, ongoing folder access), a cloud storage folder can be better, but be strict about version naming and permissions.
• If files are massive and deadlines are critical, consider specialist delivery tools designed for heavy transfers, and budget accordingly.

A quick pre-send checklist for producers

• All stems start at bar 1 (or identical start time) and are the same length.
• Sample rate and bit depth are stated in the notes.
• Filenames are consistent and descriptive (no “audio_05_final_FINAL.wav”).
• Masters and references are in separate folders.
• Link expiry matches the approval window.
• Password is set for unreleased material.
• You can re-send quickly if the client needs an extended link (without rebuilding the whole delivery).
