Disc Studio vs Express Burn

Disc Studio is a free Windows workbench for opening, browsing, editing, converting, mounting, and writing disc images. It handles formats including ISO, BIN/CUE, NRG, MDF, CCD, DMG, WIM, ESD, VHD, VHDX, VMDK, ZIP, 7Z, RAR, and DSIM. Users can add or remove image contents, extract files, and save images as ISO, DSIM, or BIN/CUE in 2048 or 2352 mode. The app browses CDs and DVDs and extracts audio tracks from mixed-mode or audio BIN/CUE images as WAV or raw BIN files. Images can be mounted through Windows, WinCDEmu, or ImDisk, with up to eight drive slots. Disc Studio burns with IMAPI, copies discs to ISO, creates bootable USB media, and supports WIM/ESD work. A command-line companion handles create, convert, mount, hash, USB, and burn jobs. Operations run locally and offline after the first download. It requires 64-bit Windows 10 or 11 and is free for personal and commercial use.

Express Burn burns audio, video, and data to CD, DVD, and Blu-ray discs on Windows and macOS. For audio, it can create MP3 or audio CDs and supports WAV, MP3, WMA, OGG, and FLAC. Video functions include DVD and Blu-ray burning, chapter management, and PAL or NTSC output. DVD authoring provides more than 20 menu templates, with the option to add custom images. Data discs can use ISO/Joliet, UDF, or Hybrid formats, and the software can create and burn ISO images. It supports recordable and rewritable media, dual-layer DVD and Blu-ray burning, bootable data discs, and disc copying. Command-line operation is available for automation and integration with other programs. The free edition does not expire, but is limited to non-commercial use and CD burning. Paid annual plans cost $34.99 a year for CD burning, $49.99 a year for CD and DVD recording, or $59.95 a year for all supported disc types. NCH says the audio and video functions are for users' own content and cannot be used to break copy or region protections.
