public AudioFormat[] getFormats()
isFormatSupported(AudioFormat)
might return
true
for certain additional formats that are missing from
the set returned by getFormats()
. The reverse is not
the case: isFormatSupported(AudioFormat)
is guaranteed to return
true
for all formats returned by getFormats()
.
Some fields in the AudioFormat instances can be set to
NOT_SPECIFIED
if that field does not apply to the format,
or if the format supports a wide range of values for that field.
For example, a multi-channel device supporting up to
64 channels, could set the channel field in the
AudioFormat
instances returned by this
method to NOT_SPECIFIED
.
isFormatSupported(AudioFormat)
public boolean isFormatSupported(AudioFormat format)
true
if
the specified format matches any of the supported formats.
format
- the audio format for which support is queried.
