Turn an audio file into a link that plays

A finished episode is usually 40 to 120 MB, so it bounces off email and is a pain to send through a chat app. Upload the MP3 here and send one link to your co-host, your guest or your editor. They press play on their phone during the commute, scrub to the part they want to check, and reply with notes. When you fix the intro, replace the file and the same link plays the new cut, so the thread you already sent stays correct. The link is not a podcast feed and will not show up in Apple Podcasts or Spotify; it is for review, private sharing and bonus content.

• ·Send a private preview to a guest before the episode is public.
• ·Share a bonus segment with newsletter subscribers without touching your feed.
• ·Swap in the corrected master and every copy of the link updates.

Phones save voice memos as M4A, and the Voice Memos app on an iPhone can only share them by AirDrop, Messages or Mail. Upload the memo here instead and you get a link you can paste anywhere: a Slack thread, a WhatsApp group, a project ticket, a Google Doc. A journalist can send an hour-long interview to an editor; a researcher can share a recorded conversation with a colleague who needs to hear tone, not just read a transcript. The receiver does not need your phone's app, an account, or to know what M4A is.

• ·M4A from an iPhone and MP3 from an Android recorder both play as is.
• ·Paste the link into a document next to your written notes.
• ·Lock a sensitive interview with a password on Pro.

A 90-minute lecture recorded on a phone is about 60 MB as an MP3, small enough for a free link. Post the link in the course page or the class group and students listen on whatever they have. Because seeking works, a student who missed the second half can drag straight to minute 45. Language teachers use the same trick for listening exercises: one link per dialogue, a QR code printed on the worksheet, and the class scans it instead of typing a URL. The view counter tells you how many students actually opened it.

• ·One link per lecture, posted where students already look.
• ·Every link comes with a QR code you can print on handouts.
• ·Re-record a muddled explanation and replace the file, same link.

A voice actor sends three takes to a client, a composer sends a draft cue to a director, a producer sends a mix for approval. The client clicks, listens, and replies with a time-stamp. Nobody has to open SoundCloud, download a WAV or ask what app to use. On Pro you can turn the download button off, so the page is listen-only, and set the link to expire after the pitch. If you are a musician sharing songs rather than work-for-hire, the music demo page covers that angle in more detail.

• ·FLAC and WAV play too, for when the client needs to hear the full quality.
• ·Listen-only pages and expiry dates are Pro settings.
• ·Name the file clearly, the title is what the client sees above the player.

The link opens a plain page: the file name as the title, the size, and the browser's standard player with play, a progress bar and a volume control. On iPhone it is the Safari player, on Android it is the Chrome player, so the controls look familiar. Tapping play starts within a second on a normal connection because the file streams rather than downloads first. A small download button sits under the player unless you turned downloads off. There is no sign-in wall, no cookie-consent maze and no app-store prompt in the way of the play button.

Spoken word does not need a high bitrate. An MP3 at 64 to 96 kbps mono is clear for a podcast or lecture and runs about 30 to 45 MB per hour, well inside the 100 MB free cap. WAV is ten times larger, roughly 10 MB per minute at CD quality, so a 20-minute WAV already passes 200 MB. If you are over the limit, export as MP3 or M4A from your editor, or convert the WAV with a free tool like Audacity or ffmpeg. Keep WAV or FLAC only when the listener really needs lossless audio, such as a mastering client.

• ·Podcast or lecture: MP3, 64 to 96 kbps, mono.
• ·Music demo: MP3 at 192 to 320 kbps, or M4A.
• ·Lossless for approval: FLAC is about half the size of the same WAV.
