ambdec - Ambisonic decoder for first and second order

ambdec_cli config_file


This manual page documents briefly the ambdec and ambdec_cli commands.

AmbDec is an Ambisonics decoder for up to 36 speakers. It can be used for both horizontal
and full 3-D systems of first, second and third order. The decoding matrices are fully
user-configurable. AmbDec has some advanced features not found on most decoders:

Dual frequency band operation. Optimal Ambisonics reproduction requires a different
decoder for low and high frequencies. This is so mainly because human perception of sound
direction uses different mechanisms at low and high frequencies. The crossover filters
used in AmbDec are phase-aligned (the two outputs are exactly in phase at all
frequencies). The combined response is equivalent to a first-order all-pass network, which
is very probably inaudible.

Speaker distance compensation. If the speakers are not all at the same distance to the
center of the listening area, this must be compensated by including the right delays and
gain corrections.

Near-field effect compensation. Ambisonics works by reconstructing the spherical harmonic
components of a sound field at the center of the listening area, using all speakers to
synthesize each of them. All non-zero order components show a near-field effect depending
on the ratio wavelength=distance, and increasing for rising order. One example of this is
the well known 'proximity effect' of directional microphones ('directional' is equivalent
to 'using non-zero order components'). Except in very large installations, where the
speaker distances will be large enough so the listening area is not in the near field,
this effect must be compensated for in order to obtain a correct reconstruction of a sound
