Bluetooth Loudspeaker 7.19

The Bluetooth Loudspeaker app allows you to transmit your voice from your Android phone to a Bluetooth speaker. Essentially, your Android device acts as a microphone and the Bluetooth speaker acts as a remote loudspeaker. This app can also function as a volume booster or megaphone for added convenience.

In the latest release (version 6.0+), the app now supports background mode (Android foreground service) when using the microphone. This means that users can exit the app and continue transmitting their voice to the remote speaker while on the home screen. To stop, simply return to the app and click on the same button (blueMic/lineOut).

In addition to its basic functionality, the new version (5.x) of Bluetooth Loudspeaker includes a built-in mp3 music player, allowing users to sing along and output their voice to the remote speaker.

This app can also connect to a Bluetooth audio adapter (receiver), enabling it to line out and connect to old Hi-Fi or amplified speakers, effectively outputting your voice. Please note that the Bluetooth audio adapter must be connected to an amplifier, not a speaker, in order to achieve optimal volume.

To ensure the best voice output quality, with minimal background noise and echo feedback, Bluetooth Loudspeaker supports wired headsets as voice input. Users can place their Android phone in their pocket and speak through the wired headset microphone, transmitting their voice wirelessly to the remote Bluetooth speaker. This feature allows for hands-free use and requires Android 6.x or above.

So what can you do with a microphone and remote loudspeaker? Who needs this app? Here are some examples:

• Singing karaoke at home or anywhere
• Boosting your voice while teaching in a classroom or lecture room
• Using it for street performances
• Utilizing it as a speaker in a conference room
• Connecting it to a PC mic-in with a 3.5mm audio cable to work as a mic for karaoke or voice recording (requires software installation on your PC)
• Utilizing it for garage sales, outdoor sales, pop-up store promotions, or other sales events
• Using it as a megaphone for tour guides at hot spots
• Engaging in outdoor activities
• Supporting your favorite sports team by singing loud in the stadium

With this app, you essentially have a wireless microphone in your pocket!

Please read the following before downloading this app:

1. This app does not automatically connect to your Bluetooth speaker. Users must manually connect their phone to the Bluetooth speaker through Settings → Bluetooth before using this app. Always test the voice output by playing music 1 or music 2 at the top.
2. This app MUST connect to an external speaker to function properly. DO NOT use the phone's internal speaker as it may produce noisy echo voices. If you still hear echo noise, please try using another Android device. Some phone models may have better noise and echo cancellation capabilities.

Additionally:

1. You need to have a Bluetooth speaker that can wirelessly connect to your Android device. The maximum loudness depends on the output of the speaker. To achieve a louder sound with less echo, set your phone volume to a maximum of 90%.
2. To reduce voice echo, avoid getting too close to the phone's microphone. Additionally, choose a device that features both a noise suppressor and an echo canceller.
3. Bluetooth Loudspeaker also supports line out to amplified speakers (requires a 3.5mm audio cable) or line headphones (please use 3-pin jack headphones). This app does not support Bluetooth headsets.
4. If your Android device supports Bluetooth 5.0 or Samsung dual audio (e.g., Galaxy Note 9, Galaxy S8+, S9+), it is possible to wirelessly connect two Bluetooth speakers at the same time.
