    AAC+ on Boom

    According to the spec, the Boom plays MP3, AAC, WMA, Ogg, FLAC, Apple lossless, WMA lossless, WAV, and AIFF music files, but will it play AAC+, an increasingly popular format for internet radio?

    Are all the specified formats natively decoded on the Boom?

    I don't know about AAC+ but this is quoted from Boom page on the website http://www.slimdevices.com/pi_boom.html :

    "Supports a wide variety of audio formats, including native support for MP3, FLAC, WAV, AIFF, WMA and Ogg Vorbis. Also transcodes from AAC, Apple Lossless, WMA Lossless, APE, MPC and WavPack."

    Yeah thanks Richie, looks like transcoding will need SC, unless someone knows different?

    AAC+ is not not supported natively in any of the products.

    This is my understanding.

    There is a large amount of common firmware in SB2, SB3, Transporter, SBR and Boom. Most of the firmware difference is to handle the hardware changes between models.

    In Boom the audio format handled is still done in the main processor and the DSP has nothing to do with audio format decoding - the DSP does additional processing on the decoded PCM stream on the way to amps/speakers.

    Thanks bpa, You've confirmed what I thought, but worth asking. I listen to a lot of AAC+ as it gives reasonable quality with reduced bandwidth requirements - perhaps it will some day be natively supported, although I am aware that processor limitations may preclude it.

    mplayer

    I would also like to see native AAC+ support. In the meantime I use SC configured with mplayer to play AAC+ streams (which gets transcoded and sent as a FLAC stream).

    See the wiki for the how-to:
