About audio files
Audio files range from compressed formats like MP3, AAC/M4A and Ogg Vorbis to lossless formats such as FLAC and ALAC and uncompressed WAV and AIFF. Compressed files are small and play everywhere, while lossless and uncompressed files keep every detail for editing, mastering and archiving.
Audio gets sent by podcasters exchanging recordings, musicians sharing demos and mixes, voice-over artists delivering takes, journalists moving interview recordings off a phone, and anyone copying a voice memo to a computer.
| Typical size | 1 MB – 2 GB |

| File extensions | .mp3, .wav, .flac, .m4a, .aac, .ogg, .aiff |
Why sending audio files is often a pain
Uncompressed recordings exceed email limits after a few minutes. Messaging apps may convert audio to low-bitrate voice-message codecs, or display it as a voice note instead of a file. Cloud music lockers sometimes transcode uploads, and many platforms strip metadata like track titles and artwork.
How to send audio files with Sendryo
- Open Sendryo on the device that has the audio files. Use any modern browser — Chrome, Safari, Edge, Firefox or Samsung Internet. Nothing to install.
- Add your audio files. Drag and drop, tap to choose, or pick a whole folder. Add as many files as you like.
- Share the 6-digit code. Tap “Get share code”, then share the code, link or QR code with the receiver.
- The receiver enters the code. Files stream directly to their device, encrypted and at original quality. They save each file or download everything as a ZIP.

Tips for sending audio files
- Match the format to the purpose: WAV or FLAC for editing and mastering, MP3 or AAC for listening and review.
- Name files clearly with version and date, for example 'Interview_Smith_2026-10-01_raw.wav', so takes don't get mixed up.
- Moving iPhone voice memos to a computer? Share them from the Voice Memos app to Files first, then add them on Sendryo.
- Batch many tracks into one transfer and let the recipient use 'Download all (ZIP)'.
Frequently asked questions
How do I send audio files without losing quality?
Send them as files directly rather than through apps that re-encode audio. Sendryo transfers files byte for byte, so a 24-bit WAV or FLAC arrives exactly as recorded, with its metadata. It's the format you choose, not the transfer, that determines quality.
Can I send recordings from my phone to my computer?
Yes. Open sendryo.com on both, add the recording on the phone and enter the code on the computer. It works across iPhone, Android, Windows and Mac. Keep the phone's browser open until the transfer finishes, especially for long recordings, since switching apps or locking the phone can pause the transfer.
What's the best audio format to send to a collaborator?
For editing or mixing, send WAV or AIFF at the project's sample rate and bit depth, or FLAC to save space without losing anything. For quick feedback, a high-bitrate MP3 or AAC is fine. Ask what your collaborator's software prefers.
Is there a size limit for sending audio files?
No limit is set by Sendryo. Because the files go straight to the other device, the only limit is the receiver’s free storage. Very large transfers work best on a computer.
