The problem
Why doesn’t pro audio go through by email?
One minute of 24-bit/48 kHz stereo WAV weighs about 16.6 MB: a Gmail attachment (25 MB) fills up with 90 seconds of music. A multitrack session or an album mastered at 24/96 runs into gigabytes.
And audio tolerates no shortcuts: converting to MP3 destroys what the mastering built — absurd when delivering a master; messaging apps recompress or truncate; private streaming lets people listen, but never delivers the files.
Between studios, you deliver files — intact. TransferNow transmits them as they are, free up to 5 GB.

The solutions
Four ways to deliver audio
Listening is not delivering: depending on the recipient — label, mastering engineer, client — here is what each option really allows.
| Method | Max size | Quality | For the recipient |
|---|---|---|---|
| TransferNow (dedicated transfer)Recommended | 5 GB free · 500 GB with an account | WAV/FLAC intact, studio quality | One click, no account |
| Convert to MP3/AAC | Weight divided by 5 to 10 | Lossy compression | Classic attachment |
| Private streaming (SoundCloud…) | Depends on the platform | Recompressed, no source file | Listening only |
| Drive / cloud storage | Depends on the account quota | Intact | Account or permissions often required |
The dedicated transfer: the master, not a listening copy
WAV, FLAC, AIFF, stems organized in folders: everything travels untouched, sample rate and bit depth included. The mastering studio receives your files, not an approximation.
MP3: fine for a demo, off-limits for a deliverable
Sending a rough mix as a 320 MP3 for approval, sure. Delivering a master or stems in a lossy format, no — every re-encoding generation degrades the signal a little more.
Private streaming: for listening, nothing more
A private SoundCloud link is perfect for gathering feedback. But the platform recompresses the audio and the recipient never gets your working files.
The cloud: workable, less direct
A drive suits a project folder shared on an ongoing basis. To deliver an album or stems once, a link with no account and no quota locked up for good stays simpler.

Frequently asked questions
How much audio can I send for free?
Up to 5 GB per transfer: about 5 hours of 24-bit/48 kHz stereo WAV, or double that in FLAC — no sign-up. With an account, up to 500 GB.
Is the audio recompressed during the transfer?
No, never: the files travel byte for byte. A 24/96 WAV arrives at 24/96, with no conversion or re-encoding.
How do I send WAV or AIFF stems to a studio?
Drag in the complete stems folder: the structure is preserved and everything goes out in a single link. The studio downloads without an account and you are notified on delivery.
Can the recipient listen before downloading?
Yes, a preview is available from the download page — handy for confirming the right version before retrieving several gigabytes.
Can I protect a track before its release?
Yes: add a password to the transfer, limit how long it stays available and track every download per recipient.
