# Send Stems, Multitracks and Mixes Without Losing Quality Last updated: 2026-09-23 A mix is only as good as the stems it starts from, so they should arrive exactly as you bounced them. storage.to sends WAV, AIFF and FLAC files untouched, up to 25GB per file, in one link your engineer or label can download without an account. [Upload Files Now](https://storage.to/) - Unlimited downloads - No speed throttling - No wait timers - No transfer quotas ## Why storage.to? - **Bit-Perfect Audio**: WAV, AIFF and FLAC files are delivered exactly as you bounced them. No transcoding to MP3, no normalising, no lower sample rate. - **Room for a Whole Session**: A 24-bit, 48kHz stereo stem is about 17MB a minute, so a full song's stems or a whole album's multitracks add up fast. Send files up to 25GB each for free. - **One Link for Every Stem**: Zip the stems folder and your engineer gets one download with every file named and in order, ready to drop into their session. - **Keep Unreleased Tracks Private**: Add a password to unreleased music and choose how long the link lasts, from 1 to 7 days. Premium, from $5/month, keeps masters and archives up permanently. ## How It Works 1. **Bounce and Name Your Stems** - Bounce every stem from the same start point at the session's sample rate and bit depth, name them clearly, and put them in one folder. 2. **Zip and Upload** - Zip the folder and drag it onto storage.to. Add a password if the track is unreleased. 3. **Send the Link** - Send the link to your mix engineer, producer or label. They download the ZIP and open it straight into their DAW. ## Perfect For - **Stems to a Mix Engineer**: Send tracked parts to a mix engineer in another city or another country. - **Masters to a Label**: Deliver final masters and alternate versions (instrumental, clean, TV mix) to a label or distributor. - **Remote Collaboration**: Swap multitrack sessions with a co-writer or session player. - **Post-Production Audio**: Hand dialogue, music and effects stems to a post-production house for a film or podcast. ## Frequently Asked Questions ### What is the best way to send music stems? Bounce the stems as WAV or AIFF, put them in one folder, zip it, upload the ZIP to storage.to and send the link. It is free up to 25GB per file and nobody needs an account. ### Will my stems be compressed? No. The file you upload is the file they download. Chat apps and some cloud players transcode audio, a download link does not. ### Should I zip my stems? Zipping keeps the stems together and in order, and the recipient gets one download instead of dozens. WAV files barely shrink when zipped, so do it for convenience, not for size. ### Can I keep unreleased music private? Yes. Add a password when you upload, send it to the recipient separately, and pick a short expiry. You can also make a link burn after its first download. ### How long does the link last? Links last 1 to 7 days on the free plan, 3 by default. Premium from $5/month keeps files permanently, useful for masters you send out again and again. ## Send Your Stems Lossless audio, up to 25GB per file, one link. No account for you or your engineer.
