The conversion is straightforward. Open the MP3 file with Mp3FileReader and then pass it to WaveFileWriter.CreateWaveFile to write the converted PCM audio to a WAV file. This will usually be 44.1kHz 16 bit stereo, but uses whatever format the MP3 decoder emits. It worked fine when I played stuff from my Amazon Fire, but when I switched to digital antenna (OTA), I didnt get any audio on my speakers. That device required you to send the audio in PCM format. Unfortunately, my Panasonic plasma TV has no option for selecting PCM audio output, so my OTA was delivering Dolby Digital to the DAC.

Audio converter is software to convert one audio format to another or alter resolution audio or process audio another way. It is used for hardware/software compatibility or sound quality optimization/improvement. See below audio converter list Mac, Windows, Linux, Android, other (including online converters), supported file types, sound quality difference, other.

Audio converter sound quality

Audio converters can convert audio content:

1. without (bit-perfect): lossless formats [both input and output] and conversion without resolution altering;
2. with sound processing.

Without sound processing

It is a lossless format repacking without audio processing (altering resolution audio, as example). It is called lossless audio converter.

In case #1, it does not matter that converter is used. There is a matter that is functionality is available. If there is real sound difference, probably, a software bug is there.

When CUE+compressed file is splitted, the splitting may be provided without re-encoding. As rule, the compressed files are divided by frames. And track border may be placed into a frame. It cause placement of part of one track content to neighbour track. Re-encoding can solve this issue.

When lossless file (FLAC, WAV, etc.) are splitted, re-encoding don't cause quality losses. But re-encoding of lossy file cause losses in splitting.

With sound processing

In case #2 (resampling, lossy compressing, bit depth altering, etc.) a converter defines sound quality (processing distortions).

As rule, speed of conversion depends on sound quality (lesser speed - higher sound quality).

Dithering is recommended for:

• bit depth reducing to 16-bit, or
• 16 to 16 bit file processing.

Some albums are uninterrupted (operas, live concerts). They have non-zero levels at track borders. It can cause artefacts at borders after resampling and other processing. To fix the issue True Gapless technology is used.

Which audio converter is best?

It depends on what you want primarily.

If you want sound quality - it is converter that provides minimal distortions. In audio character of distortions (accounting psychoacoustics) can impact sound. So there are no exact figures, that define the best audio converter. As rule, a proper blind hearing test can give a more exact answer to the question.

Metadata, album art

Audio converters can export album art and text metadata from source to target file.

Also, metadata editor can alter text metadata and insert/replace/delete album cover.

Some metadata formats (mp3, flac, dsf and some other) allow assigning several artworks into a single file.

Wav To Pcm Converter

DSD converter is software to convert DSD audio files to other formats and back. DSD audio files have extensions DSF, DFF, ISO (1-bit audio). As target or source formats PCM multibit formats (WAV, FLAC, AIFF, mp3, etc. files and CD-audio disks) can be used. Also such converter can resample DSD files. Read below how to work the converter.

Format DSD is implementation of sigma-delta modulation. There used sample rates that multiple 44100 Hz:

• 2.8 MHz = 2 822 400 Hz = 44100 Hz x 64 times;
• 5.6 MHz = 5 644 800 Hz = 44100 Hz x 128 times;
• 11.2 MHz = 11 289 600 Hz = 44100 Hz x 256 times;
• 22.6 MHz = 22 579 200 Hz = 44100 Hz x 512 times;
• 45.2 MHz = 45 158 400 Hz = 44100 Hz x 1024 times;
• etc.

Bit depth is 1 bit.

What inside DSD converter

Software DSD converter can have inside:

1. PCM (multibit) modulator to delta-sigma modulation (1-bit), or

2. Sigma-delta demodulator (1-bit) to PCM (multibit), or

3. Both: modulator and demodulator.

4. Resampler.

Structure of DSD converter

DSD modulator provide decreasing number of bits. It lead to increasing noise level (error).

Most useful part of audio signal placed in range 0 ... 20 kHz. The modulator 'push' energy of noise in range above 20 kHz (called as noise shaping).

Demodulator provide filtering this noise. After the filtering remains only the most useful audio signal.

DSD modulator (sigma-delta modulator)

Sigma-delta modulator (PCM to DSD) is sophisticated audio processing. It is system with feedback. Hence it can lose stability. If sigma-delta modulator (DSD modulator) lose stability, need restart it. As rule it can't return to stable mode without external impact.

DSD modulator

In general, desing of sigma delta modulator is compromise between stability and noise level. More significant pushing of noise energy out of audible range, may lead to lose stability. DSD modulator can lose stability due overload.

For achieving better signal/noise ratio inside audible range and keeping stability, frequency band out of audible range must have reserve by width. It may be achieved via increasing sample rate.

Sample rate increasing is easier way to have wider band with lower noise.

Unfortunatelly, I don't know exactly history of creating DSD, but, looks like, sample rate D64 was designed for transmitting 20 kHz band. As rule, DSD demodulator is easier, comparing PCM one (read more). So replacing 44 kHz/16 bit to DSD64 may give some technical advantages for implementation.

For transfering of 100 kHz-band signal with keeping or decreasing noise floor, easiest way is sample rate increasing.

DSD demodulator

Sigma-delta demodulator (DSD to PCM) or DSD demodulator is low frequency filter, that remove modulation noise, located above audible range.

DSD demodulator

This filter have 3 features:

• pass band (minimum 0 ... 20 kHz);
• stop band (band where DSD modulator noise is suppressed);
• transient band (band between pass and stop bands).

Wider transient band allow decrease ringing audio, but pass more energy of noise of DSD modulator.

If expand pass band, DSD's noise energy also increased, pass band become narrower, ringing increased.

So DSD demodulator is balanced technical decision.

Resampling DSD

Resampling DSD is digital audio processing. Performed via multiple upsampling/downsampling with digital filtering.

Before resampling file DSD converted without loses to multibit audio stream suitable for processing . After it processed and converted back to DSD via modulator.

Resampling 1-bit audio cause little losses, comparable with losses for PCM resampling. There losses defined by distortions of used implementation of processing.

However, playback apparatus may have different distortion level for different sample rates. Hence resampling may give benefits, if DSD converted to sample rate that works with minimal distortions on used DAC.

Playback hardware may have different distortions for different modes (sample rate, bit depth, PCM/DSD).
Resampling DSD or conversion PCM to DSD and DSD to PCM may give benefits, if target format suitable for DAC mode, that cause minimal distortions.
