-: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)
-

- * linear2ulaw() accepts a 14-bit signed integer and encodes it as u-law data
- * stored in an unsigned char. This function should only be called with
- * the data shifted such that it only contains information in the lower
- * 14-bits.
- *
- * In order to simplify the encoding process, the original linear magnitude
- * is biased by adding 33 which shifts the encoding range from (0 - 8158) to
- * (33 - 8191). The result can be seen in the following encoding table:
- *
- * Biased Linear Input Code Compressed Code
- * ------------------------ ---------------
- * 00000001wxyza 000wxyz
- * 0000001wxyzab 001wxyz
- * 000001wxyzabc 010wxyz
- * 00001wxyzabcd 011wxyz
- * 0001wxyzabcde 100wxyz
- * 001wxyzabcdef 101wxyz
- * 01wxyzabcdefg 110wxyz
- * 1wxyzabcdefgh 111wxyz
- *
- * Each biased linear code has a leading 1 which identifies the segment
- * number. The value of the segment number is equal to 7 minus the number
- * of leading 0's. The quantization interval is directly available as the
- * four bits wxyz. * The trailing bits (a - h) are ignored.
- *
- * Ordinarily the complement of the resulting code word is used for
- * transmission, and so the code word is complemented before it is returned.
- *

- * John Wiley & Sons, pps 98-111 and 472-476.

-** Findfit tries to locate a sample within another sample. Its main use
-** is in echo-cancellation (to find the feedback of the output signal in
-** the input signal).
-** The method used is as follows:
-**
-** let R be the reference signal (length n) and A the input signal (length N)
-** with N > n, and let all sums be over i from 0 to n-1.
-**
-** Now, for each j in {0..N-n} we compute a factor fj so that -fj*R matches A
-** as good as possible, i.e. sum( (A[j+i]+fj*R[i])^2 ) is minimal. This
-** equation gives fj = sum( A[j+i]R[i] ) / sum(R[i]^2).
-**
-** Next, we compute the relative distance between the original signal and
-** the modified signal and minimize that over j:
-** vj = sum( (A[j+i]-fj*R[i])^2 ) / sum( A[j+i]^2 ) =>
-** vj = ( sum(A[j+i]^2)*sum(R[i]^2) - sum(A[j+i]R[i])^2 ) / sum( A[j+i]^2 )
-**
-** In the code variables correspond as follows:
-** cp1 A
-** cp2 R
-** len1 N
-** len2 n
-** aj_m1 A[j-1]
-** aj_lm1 A[j+n-1]
-** sum_ri_2 sum(R[i]^2)
-** sum_aij_2 sum(A[i+j]^2)
-** sum_aij_ri sum(A[i+j]R[i])
