EZ CD Audio Converter

Audio Converter

Convert audio files freely between all supported formats that include FLAC, MP3, M4A, AAC, Opus, DSD, WAV, AIFF, Apple Lossless, and Vorbis. Batch convert unlimited number of files at once and keep the folder structure and file names. Optionally customize output folder and output filenames with metadata tags. Speed up the audio file conversions on multi-core CPUs by running up to 64 parallel audio converters.

Preserve all metadata and album art in audio file conversions. Get metadata from 6 online metadata services, add or modify any metadata prior conversion. Or use the metadata editor to save the updated metadata back to the source audio files.

CD Ripper

Securely extract audio tracks from CDs in bit perfect audio quality with advanced error detection and two-pass sector-by-sector CRC verification. Convert CDs to FLAC, MP3, AAC, M4A, WAV, Apple Lossless, Opus, DSD, ALAC, Ogg Vorbis, and more audio file formats. Get high quality metadata from 6 online music metadata services. Read and preserve CD-Text, ISRC, UPC/EAN, and pre-gap information. De-emphasize audio CDs that have pre-emphasis. Save CD information and status of the audio extraction into ripping log.

Disc Burner

Easily burn audio CDs from all audio file formats with CD-Text information. Burn MP3 discs and data discs.

Audio Quality

• Ultra precise (64-bit floating point) audio engine
• Professional quality sample rate converter
• Professional quality DSD encoder with stabilized 8th order noise-shaper without phase distortion
• Professional quality DSD decoder with high quality noise-filtering
• Bit-exact gapless conversion of all audio file formats
• High quality dithering (RTN, RPDF, TPDF, Noise-shaped)
• Convert between DSD and PCM format in lossless quality
• Convert between DSD file formats in bit-exact DSD mode (DSF, DFF, WavPack DSD, SACD, SACD ISO)
• Audio is always preserved in ultra-precise format during the audio conversions

Metadata

All metadata tags are supported (51 predefined + custom tags, album art + all images). Advanced metadata editor for easy editing of all metadata. Use as a metadata editor and edit all metadata of existing files. Keep all metadata on audio file format conversions.

Online metadata services

Download high quality metadata and cover art from 6 online metadata services. Metadata can be retrieved automatically or searched manually with keywords.

Codecs

All audio codecs are included in the software. There is no need to download additional codecs from other sources.

All encoders and decoders operate in high resolution audio mode (in 32-bit float or greater accuracy). It ensures that there is no additional quantization or dithering noise when converting from high resolution source (e.g. 24-bit FLAC to MP3) or when transcoding between lossy formats (e.g. M4A to MP3).
