:mod:`audioop` --- Manipulate raw audio data
|
||||
============================================
|
||||
|
||||
.. module:: audioop
|
||||
:synopsis: Manipulate raw audio data.
|
||||
:deprecated:
|
||||
|
||||
.. deprecated-removed:: 3.11 3.13
|
||||
The :mod:`audioop` module is deprecated
|
||||
(see :pep:`PEP 594 <594#audioop>` for details).
|
||||
|
||||
--------------
|
||||
|
||||
The :mod:`audioop` module contains some useful operations on sound fragments.
|
||||
It operates on sound fragments consisting of signed integer samples 8, 16, 24
|
||||
or 32 bits wide, stored in :term:`bytes-like objects <bytes-like object>`. All scalar items are
|
||||
integers, unless specified otherwise.
|
||||
|
||||
.. versionchanged:: 3.4
|
||||
Support for 24-bit samples was added.
|
||||
All functions now accept any :term:`bytes-like object`.
|
||||
String input now results in an immediate error.
|
||||
|
||||
.. index::
|
||||
single: Intel/DVI ADPCM
|
||||
single: ADPCM, Intel/DVI
|
||||
single: a-LAW
|
||||
single: u-LAW
|
||||
|
||||
This module provides support for a-LAW, u-LAW and Intel/DVI ADPCM encodings.
|
||||
|
||||
.. This para is mostly here to provide an excuse for the index entries...
|
||||
|
||||
A few of the more complicated operations only take 16-bit samples, otherwise the
|
||||
sample size (in bytes) is always a parameter of the operation.
|
||||
|
||||
The module defines the following variables and functions:
|
||||
|
||||
|
||||
.. exception:: error
|
||||
|
||||
This exception is raised on all errors, such as unknown number of bytes per
|
||||
sample, etc.
|
||||
|
||||
|
||||
.. function:: add(fragment1, fragment2, width)
|
||||
|
||||
Return a fragment which is the addition of the two samples passed as parameters.
|
||||
*width* is the sample width in bytes, either ``1``, ``2``, ``3`` or ``4``. Both
|
||||
fragments should have the same length. Samples are truncated in case of overflow.
|
||||
|
||||
|
||||
.. function:: adpcm2lin(adpcmfragment, width, state)
|
||||
|
||||
Decode an Intel/DVI ADPCM coded fragment to a linear fragment. See the
|
||||
description of :func:`lin2adpcm` for details on ADPCM coding. Return a tuple
|
||||
``(sample, newstate)`` where the sample has the width specified in *width*.
|
||||
|
||||
|
||||
.. function:: alaw2lin(fragment, width)
|
||||
|
||||
Convert sound fragments in a-LAW encoding to linearly encoded sound fragments.
|
||||
a-LAW encoding always uses 8 bits samples, so *width* refers only to the sample
|
||||
width of the output fragment here.
|
||||
|
||||
|
||||
.. function:: avg(fragment, width)
|
||||
|
||||
Return the average over all samples in the fragment.
|
||||
|
||||
|
||||
.. function:: avgpp(fragment, width)
|
||||
|
||||
Return the average peak-peak value over all samples in the fragment. No
|
||||
filtering is done, so the usefulness of this routine is questionable.
|
||||
|
||||
|
||||
.. function:: bias(fragment, width, bias)
|
||||
|
||||
Return a fragment that is the original fragment with a bias added to each
|
||||
sample. Samples wrap around in case of overflow.
|
||||
|
||||
|
||||
.. function:: byteswap(fragment, width)
|
||||
|
||||
"Byteswap" all samples in a fragment and returns the modified fragment.
|
||||
Converts big-endian samples to little-endian and vice versa.
|
||||
|
||||
.. versionadded:: 3.4
|
||||
|
||||
|
||||
.. function:: cross(fragment, width)
|
||||
|
||||
Return the number of zero crossings in the fragment passed as an argument.
|
||||
|
||||
|
||||
.. function:: findfactor(fragment, reference)
|
||||
|
||||
Return a factor *F* such that ``rms(add(fragment, mul(reference, -F)))`` is
|
||||
minimal, i.e., return the factor with which you should multiply *reference* to
|
||||
make it match as well as possible to *fragment*. The fragments should both
|
||||
contain 2-byte samples.
|
||||
|
||||
The time taken by this routine is proportional to ``len(fragment)``.
|
||||
|
||||
|
||||
.. function:: findfit(fragment, reference)
|
||||
|
||||
Try to match *reference* as well as possible to a portion of *fragment* (which
|
||||
should be the longer fragment). This is (conceptually) done by taking slices
|
||||
out of *fragment*, using :func:`findfactor` to compute the best match, and
|
||||
minimizing the result. The fragments should both contain 2-byte samples.
|
||||
Return a tuple ``(offset, factor)`` where *offset* is the (integer) offset into
|
||||
*fragment* where the optimal match started and *factor* is the (floating-point)
|
||||
factor as per :func:`findfactor`.
|
||||
|
||||
|
||||
.. function:: findmax(fragment, length)
|
||||
|
||||
Search *fragment* for a slice of length *length* samples (not bytes!) with
|
||||
maximum energy, i.e., return *i* for which ``rms(fragment[i*2:(i+length)*2])``
|
||||
is maximal. The fragments should both contain 2-byte samples.
|
||||
|
||||
The routine takes time proportional to ``len(fragment)``.
|
||||
|
||||
|
||||
.. function:: getsample(fragment, width, index)
|
||||
|
||||
Return the value of sample *index* from the fragment.
|
||||
|
||||
|
||||
.. function:: lin2adpcm(fragment, width, state)
|
||||
|
||||
Convert samples to 4 bit Intel/DVI ADPCM encoding. ADPCM coding is an adaptive
|
||||
coding scheme, whereby each 4 bit number is the difference between one sample
|
||||
and the next, divided by a (varying) step. The Intel/DVI ADPCM algorithm has
|
||||
been selected for use by the IMA, so it may well become a standard.
|
||||
|
||||
*state* is a tuple containing the state of the coder. The coder returns a tuple
|
||||
``(adpcmfrag, newstate)``, and the *newstate* should be passed to the next call
|
||||
of :func:`lin2adpcm`. In the initial call, ``None`` can be passed as the state.
|
||||
*adpcmfrag* is the ADPCM coded fragment packed 2 4-bit values per byte.
|
||||
|
||||
|
||||
.. function:: lin2alaw(fragment, width)
|
||||
|
||||
Convert samples in the audio fragment to a-LAW encoding and return this as a
|
||||
bytes object. a-LAW is an audio encoding format whereby you get a dynamic
|
||||
range of about 13 bits using only 8 bit samples. It is used by the Sun audio
|
||||
hardware, among others.
|
||||
|
||||
|
||||
.. function:: lin2lin(fragment, width, newwidth)
|
||||
|
||||
Convert samples between 1-, 2-, 3- and 4-byte formats.
|
||||
|
||||
.. note::
|
||||
|
||||
In some audio formats, such as .WAV files, 16, 24 and 32 bit samples are
|
||||
signed, but 8 bit samples are unsigned. So when converting to 8 bit wide
|
||||
samples for these formats, you need to also add 128 to the result::
|
||||
|
||||
new_frames = audioop.lin2lin(frames, old_width, 1)
|
||||
new_frames = audioop.bias(new_frames, 1, 128)
|
||||
|
||||
The same, in reverse, has to be applied when converting from 8 to 16, 24
|
||||
or 32 bit width samples.
|
||||
|
||||
|
||||
.. function:: lin2ulaw(fragment, width)
|
||||
|
||||
Convert samples in the audio fragment to u-LAW encoding and return this as a
|
||||
bytes object. u-LAW is an audio encoding format whereby you get a dynamic
|
||||
range of about 14 bits using only 8 bit samples. It is used by the Sun audio
|
||||
hardware, among others.
|
||||
|
||||
|
||||
.. function:: max(fragment, width)
|
||||
|
||||
Return the maximum of the *absolute value* of all samples in a fragment.
|
||||
|
||||
|
||||
.. function:: maxpp(fragment, width)
|
||||
|
||||
Return the maximum peak-peak value in the sound fragment.
|
||||
|
||||
|
||||
.. function:: minmax(fragment, width)
|
||||
|
||||
Return a tuple consisting of the minimum and maximum values of all samples in
|
||||
the sound fragment.
|
||||
|
||||
|
||||
.. function:: mul(fragment, width, factor)
|
||||
|
||||
Return a fragment that has all samples in the original fragment multiplied by
|
||||
the floating-point value *factor*. Samples are truncated in case of overflow.
|
||||
|
||||
|
||||
.. function:: ratecv(fragment, width, nchannels, inrate, outrate, state[, weightA[, weightB]])
|
||||
|
||||
Convert the frame rate of the input fragment.
|
||||
|
||||
*state* is a tuple containing the state of the converter. The converter returns
|
||||
a tuple ``(newfragment, newstate)``, and *newstate* should be passed to the next
|
||||
call of :func:`ratecv`. The initial call should pass ``None`` as the state.
|
||||
|
||||
The *weightA* and *weightB* arguments are parameters for a simple digital filter
|
||||
and default to ``1`` and ``0`` respectively.
|
||||
|
||||
|
||||
.. function:: reverse(fragment, width)
|
||||
|
||||
Reverse the samples in a fragment and returns the modified fragment.
|
||||
|
||||
|
||||
.. function:: rms(fragment, width)
|
||||
|
||||
Return the root-mean-square of the fragment, i.e. ``sqrt(sum(S_i^2)/n)``.
|
||||
|
||||
This is a measure of the power in an audio signal.
|
||||
|
||||
|
||||
.. function:: tomono(fragment, width, lfactor, rfactor)
|
||||
|
||||
Convert a stereo fragment to a mono fragment. The left channel is multiplied by
|
||||
*lfactor* and the right channel by *rfactor* before adding the two channels to
|
||||
give a mono signal.
|
||||
|
||||
|
||||
.. function:: tostereo(fragment, width, lfactor, rfactor)
|
||||
|
||||
Generate a stereo fragment from a mono fragment. Each pair of samples in the
|
||||
stereo fragment are computed from the mono sample, whereby left channel samples
|
||||
are multiplied by *lfactor* and right channel samples by *rfactor*.
|
||||
|
||||
|
||||
.. function:: ulaw2lin(fragment, width)
|
||||
|
||||
Convert sound fragments in u-LAW encoding to linearly encoded sound fragments.
|
||||
u-LAW encoding always uses 8 bits samples, so *width* refers only to the sample
|
||||
width of the output fragment here.
|
||||
|
||||
Note that operations such as :func:`.mul` or :func:`.max` make no distinction
|
||||
between mono and stereo fragments, i.e. all samples are treated equal. If this
|
||||
is a problem the stereo fragment should be split into two mono fragments first
|
||||
and recombined later. Here is an example of how to do that::
|
||||
|
||||
def mul_stereo(sample, width, lfactor, rfactor):
|
||||
lsample = audioop.tomono(sample, width, 1, 0)
|
||||
rsample = audioop.tomono(sample, width, 0, 1)
|
||||
lsample = audioop.mul(lsample, width, lfactor)
|
||||
rsample = audioop.mul(rsample, width, rfactor)
|
||||
lsample = audioop.tostereo(lsample, width, 1, 0)
|
||||
rsample = audioop.tostereo(rsample, width, 0, 1)
|
||||
return audioop.add(lsample, rsample, width)
|
||||
|
||||
If you use the ADPCM coder to build network packets and you want your protocol
|
||||
to be stateless (i.e. to be able to tolerate packet loss) you should not only
|
||||
transmit the data but also the state. Note that you should send the *initial*
|
||||
state (the one you passed to :func:`lin2adpcm`) along to the decoder, not the
|
||||
final state (as returned by the coder). If you want to use
|
||||
:class:`struct.Struct` to store the state in binary you can code the first
|
||||
element (the predicted value) in 16 bits and the second (the delta index) in 8.
|
||||
|
||||
The ADPCM coders have never been tried against other ADPCM coders, only against
|
||||
themselves. It could well be that I misinterpreted the standards in which case
|
||||
they will not be interoperable with the respective standards.
|
||||
|
||||
The :func:`find\*` routines might look a bit funny at first sight. They are
|
||||
primarily meant to do echo cancellation. A reasonably fast way to do this is to
|
||||
pick the most energetic piece of the output sample, locate that in the input
|
||||
sample and subtract the whole output sample from the input sample::
|
||||
|
||||
def echocancel(outputdata, inputdata):
|
||||
pos = audioop.findmax(outputdata, 800) # one tenth second
|
||||
out_test = outputdata[pos*2:]
|
||||
in_test = inputdata[pos*2:]
|
||||
ipos, factor = audioop.findfit(in_test, out_test)
|
||||
# Optional (for better cancellation):
|
||||
# factor = audioop.findfactor(in_test[ipos*2:ipos*2+len(out_test)],
|
||||
# out_test)
|
||||
prefill = '\0'*(pos+ipos)*2
|
||||
postfill = '\0'*(len(inputdata)-len(prefill)-len(outputdata))
|
||||
outputdata = prefill + audioop.mul(outputdata, 2, -factor) + postfill
|
||||
return audioop.add(inputdata, outputdata, 2)
