Opus Player is an audio player designed for the opus format, which offers additional features for managing audio messages. It is compatible with most file explorers on Google Play and allows users to choose the audio output, selecting the main speaker or the earpiece. Opus Player is the best audio manager for WhatsApp's voice notes, providing features for deleting, sharing, and organizing audio messages.

One of the most notable features of Opus Player is the ability to share audio as a Facebook post, a WhatsApp status, or an Instagram story. Users can also switch their audio output between the standard multimedia and the voice call's speaker, making it easier to use WhatsApp without any problems with the proximity sensor. Additionally, Opus Player takes a history of all your voice messages, received and sent, and shows them to you in order of date, giving you the possibility to easily find an old voice note and share it with other apps.

Opus Player also allows users to organize their audio messages into categories, giving each category a name and an image. Users can filter the voice notes by choosing to show only those belonging to one or more categories. Moreover, users can delete all the voice notes in a category with only one click. Other features include the ability to rename voice notes, set a text note, and select the folder in which Opus Player must search the .opus files.

Overall, Opus Player is a useful app for managing audio messages, especially for WhatsApp's voice notes. It saves users time when they need to find old voice messages and allows them to listen to new received voice notes directly from the app without notifying WhatsApp. Users can also share the voice messages on the main social networks, including Facebook, Twitter, WhatsApp status, and Instagram stories.
