Esperanto AU, in detail

Understanding Esperanto AU files

Esperanto is a constructed language with a single standardized form and no regional dialects. In practice, pronunciation varies with each speaker's native language, so recordings from international gatherings can mix many different accents in one conversation.

AU technical specifications

Codec
µ-law, A-law, or linear PCM (Audacity block files use 32-bit float PCM)
Container
AU (Sun audio)
Typical bitrate
Varies by encoding; classic 8 kHz µ-law files are 64 kbps
Sample rate
8–48 kHz typical (8 kHz for classic µ-law); the header supports arbitrary rates, and Audacity chunks use the project's rate
Compression
Container (varies)

Esperanto at a glance

Esperanto AU conversion FAQ

Frequently asked questions

How to improve the accuracy of your Esperanto transcripts?

Start by improving the quality of the Esperanto AU file that you upload to Sonix. Please use high quality recording equipment, recording in a quiet environment, and ensure that your speakers are speaking clearly to ensure that your transcript is as accurate as possible.

Any advice for the Esperanto AU file that I upload?

Yes, please do not over-compress or over-filter the audio track of your Esperanto AU file. By uploading a high quality version of your audio, we can give you the best level of accuracy.

Aside from AU, do you support other types of audio/video files?

Yes, we do! You can convert the following file types in Esperanto with Sonix:

Why is my Audacity project folder full of small AU files?

Older versions of Audacity split a project's audio into small AU block files inside a _data folder so long tracks could be edited efficiently, and the .aup project file reassembles them in order. Avoid moving or renaming these chunks; open the project and export the audio instead.

How do I play a standalone AU file?

Standalone AU files use the Sun audio format and open in players such as VLC and editors such as Audacity. Converting to WAV or MP3 gives the broadest compatibility with modern software and devices.

Can Sonix transcribe Esperanto audio and video?

Yes. Upload your recording, select Esperanto as the spoken language, and Sonix generates a transcript you can edit alongside the original audio and export as documents or subtitles.

Does Esperanto transcription handle different accents?

Esperanto speakers carry accents from their native languages, so pronunciation varies from speaker to speaker. Sonix's browser editor syncs the transcript to the audio, making it easy to review and correct accent-related mistakes.

Will Esperanto's special characters like ĉ and ŭ appear in my transcript?

Yes. Transcripts and exports use standard Unicode text, so the six diacritic letters (ĉ, ĝ, ĥ, ĵ, ŝ, ŭ) are preserved in documents and subtitle files.
